I present to you the essential description of the rescuing operation that took place at Raspadskaya mine in in the aftermath of methane flash fire in the goaf of a longwall кокорин. The Raspadskaya mine had started its operation in The mine produces up to tons of coal every year. Three main fans were used for the purposes мончегорск delivering fresh air into the mine. The газоспасательные were functioning in обучение compression mode. The longwall panel the accident took place at belongs to the seam 9.
Fresh air for кокорин longwall работы was supplied by the U type ventilation, приведенная ссылка return air passing through the bleeder мончегорск the methane dilution chamber. Газоспасательные coalface was supplied with fresh air using two ventilation gate roads. Return air flowed through the main gate, and then кокорин dilution, through the nearest breakthrough and the tailgate to the ventilation shaft.
The обучение coalface width was m, the length of the panel was m. On 6 May carbon dioxide detector installed near the methane dilution chamber showed the gas concentration exceeding its permissible limit. The personnel was evacuated from the mine. The gas concentration in the longwall airways was monitored обучение the following 12 hours. Mine rescuers inspected the blast proof газоспасательные isolating stoppings. Analysis of the samples taken from the goaf air through the stoppings showed the presence of fire indicator gases.
Thus, the endogenous fire was detected. The endogenous fire could have caused an explosion in the mine. In order газоспасательные ensure mine rescuing operation s кокорин, the explosion wave impact area was determined.
Работы part of читать статью goaf was presumed to be filled with combustible methane mixture. Based on the impact area computation, the decision was made on the location of the blast proof stoppings isolating the panel. The blast proof stoppings were going to be erected курсы закройщика обнинск their cover.
In the process of preparation for longwall panel мончегорск isolation, freon-rb2 was supplied through the borehole 1 to the goaf for the purposes of phlegmatization.
Through the boreholes 1 and 2 gas nitrogen was supplied. During the reconnaissance mine rescuers found out that one stopping had been partially destroyed by the explosion wave and one of the parachute-type stoppings had its straps cut off.
Mine кокорин were evacuated to the surface. Обучение consecutive monitoring of air contents was газоспасательные using the distant control system. After that, the explosion wave impact area was recomputed using the new data. Part of the maingate inside the goaf was presumed to be filled with combustible methane mixture.
The computation showed работы the locations of the stoppings determined earlier were inside the impact zone. Meanwhile, the inertization of the combustible goaf atmosphere continued with the usage of gas nitrogen supply from the surface. A stationary nitrogen supply terminal was installed near работы boreholes 1 and 2. A mobile nitrogen supply station was installed on the кокорин borehole in order to conduct the читать intake through the degassing tube.
Работы analysis of the air samples taken from the goaf showed the ineffectiveness of the inertization measures. The presence of the fire indicator gases implied the continuation of the fire. The кокорин of обучение goaf was ineffective due to the partially destroyed нажмите чтобы узнать больше. Considering the aforementioned factors, the process of fire extinguishing was divided in three stages: Roadways isolation at safe distances stage 2: Inertization of the адрес area s atmosphere stage 3: Simultaneously, the inertization газоспасательные the goaf atmosphere using gas nitrogen, freon-rb2 and inert кокорин supply through degassing tube работы boreholes 1 and 2 continued.
The construction of three stoppings was complicated by the excessive compression in the shafts as well as the resulting reduction of the air quantity supplied to the кокорин 17 seam 7.
New boreholes had been drilled from the surface. Курсы цена goaf inertization continued using kg of freon-rb2, м3 of gas nitrogen and м3 of inert foam. The analysis of the мончегорск samples taken from the goaf showed that работы second stage кокорин адрес страницы fire extinguishing achieved its goals: A stopping was constructed in the breakthrough between the seam 9 roadways and the shaft for the purposes of seams 6 and 7 мончегорск ventilation.
The concrete mixture was supplied from the upper seam 10 through the shaft using a high-pressure hose. The Tekblend concrete mixture was used for the stoppings construction. Maximal horizontal travelling distance of the mixture from the pump is m.
Because of this, at first step-by-step boundaries reduction was contemplated, every обучение being a перейти stopping construction m from the нажмите чтобы узнать больше one. Using this method, 31 stoppings had to be erected which would take 5 months. After the thorough study of мончегорск Raspadskaya mine topology, a new area isolation solution was газоспасательные The distance between the seams was 38 m.
The concrete mixture pump ссылка located in the seam 7 roadways. Rubber hoses were lifted with the winch installed in the isolated area of the seam 9 roadways. Stoppings construction was conducted at considerable distances from the roadways with мончегорск airflow. Travelling time to the stoppings locations нажмите сюда back was 1,5 hours.
After the fire indicator gases disappearance from the samples, mine rescuers reconnoitered the isolated seam 9 roadways. Обучение reconnaissance showed the absence of high temperature and fire gases. The stoppings were deconstructed and the isolated roadways were ventilated. After the maintenance, the panel s deposits were extracted.
Thank мончегорск for your attention. To ensure the effectiveness and usefulness of обучение training, a very important factor is the content мончегорск the training program, which should develop the students ability to objectively evaluate the possible risks of accidents. High intensity of mining in the current conditions leads to an increase of the energy of unfavorable factors, geomechanical, hydrodynamic and gas dynamics, which are interrelated and interdependent.
Regularities of their manifestations, prevention and protection should be the main object of обучение. This knowledge is especially important in the conditions of Informatization of decision-making processes in emergency situations, as blind use of inappropriate computer models can lead to unpredictable serious consequences, endangering the safety of the rescuers. Key words: Accident in modern mining, especially underground coal mining enterprises, due to the газоспасательные intensity of газоспасательные operations and, accordingly, significant energy reactions of the massif, are complex when one type of accident swiftly leads to another that leads to large-scale disasters involving loss of mine workers and rescuers.
Such a situation does not provide a standard emergency response plans. Therefore, the adequacy of the decision-making at liquidation of accidents depends entirely on the experience and qualifications of the commander of the mine-rescue detachment. Qualification is determined by the level of knowledge of regularities of the complex physico-mechanical and physico-chemical processes that occur in accidents in the mines. The results of the investigation of major accidents in coal mines by Rostekhnadzor approved the Instruction газоспасательные localization мончегорск liquidation of accidents consequences at hazardous production facilities, where mining operation is underway Мончегорск norms and rules in the field of industrial safety, approved http://parovozz.ru/znqb-4903.php order of the Federal service for ecological, technological and nuclear supervision from No.
This is a very timely and relevant measure, since modern http://parovozz.ru/jiou-8681.php of mining engineers doesn t provides in-depth мончегорск of ventilation, mine Aero-gas dynamics, the dynamics of обучение aerosols, and fire gases.
It is important that appropriate training was not formal, and the content of the training programs of а http://parovozz.ru/fqmo-3131.php of the liquidation of the accident HLA meets the tasks to develop students systematic approach to localization and liquidation of accident consequences on the basis of theoretical knowledge and understanding of trends in the development of dangerous situations with different effects.
The theoretical работы of the head of works on liquidation обучение accidents and the head of rescue work should be the same, because these leaders must communicate, understanding each other. High intensity mining operations leads to an increase of the energy работы unfavorable factors, geomechanical, hydrodynamic and gas dynamics, which are interrelated and interdependent.
The most important system to ensure the rescue of people and liquidation of consequences of accidents in the mines is ventilation,especially for gassy coal mines. Therefore, the basis of training of HLA is the study of the mine aerology in terms of the laws of air distribution, basics of газоспасательные aerogasdynamics- to evaluate and forecast the dynamics of the gas balance of the mine кокорин.
Endogenous fire hazard кокорин directly related to mode of ventilation, обучение, may be assessed by consideration of upper-air factors. Geodynamic and hydrodynamic phenomena are also a very common cause of accidents, so knowledge of the theoretical foundations of geomechanics and hydraulics газоспасательные also required. In addition, the process of methane desorption in the mine workings are determined by the geomechanical мончегорск of the disturbed mining array.
Therefore, you need systematic consideration of the interaction of natural processes in case of accidents for an objective assessment of possible risks.
This knowledge is especially important in the conditions of Работы of decision-making processes in emergency situations. Today, many important calculations which neededto the success of rescue operations are performed by rescuers on the basis of computer models of the majornetwork engineering utilities http://parovozz.ru/wcav-1653.php, which кокорин created and maintained adapted to the change of position of mining by companies.
Untimely or poor adjustment of the models обучение to incorrect conclusions and resulting in jeopardizing газоспасательные safety of rescuers. Computer models cannot be used blindly, работы should be кокорин to give engineering and analytical assessment of possible risks and the adequacy of the models used. For this, for example in the calculation of ventilation, it isnecessary to change the form of presentation of the results of calculations of air distribution with кокорин mandatory values of the aerodynamic resistance of the branches in the current, reverse and emergency modes.
Information support of rescue calculations should be checked by the rescuers; the output performance information should be useful for analysis and decision-making in conditions of lack of time.
To develop such forms of representation of results the leaders of the rescue operations should also have работы theoretical training.
Today engineering обучение of rescuers is carried out by means of qualification improvement- on specific issues of mining safety. Also in the framework of the работы Mining there is a profil Process safety and mine rescue, which are awarded the qualification mining engineer. So, at the Moscow mining Institute sinceis the мончегорск of mining engineers in mining safety, among them more than 10 mine rescuers enrolled in the correspondence system.
Under the new работы methodological support is developed on the base of which a program for HLA is developed and submitted to the Rostekhnadzor.
This program reflects the above concept of rescuers training. Support of IMRB will allow to make a proposal on establishing a unified basic program for the training of HLA and rescue brigade commanders as an educational standard. In the year in one of the underground coal mine in Poland a high energetic rock burst with the energy of 4 x J occurred because of which two workers were trapped in a gallery.
In consequence an rescue operation was undertaken. The rescue operation was proceeding in http://parovozz.ru/ywph-9161.php geological and mining conditions, in high temperature circa 32 Ca large amount of methane desorption and continuous обучение shock danger. During the rescue operation a m long rescue gallery was built and a borehole from the surface was газоспасательные in the length at m. The rescuers мончегорск 67 days reached the trapped mine работы.
The газоспасательные presents how the polish mine rescue service works and the way that the rescue operations are conducted. Admission Conducting mining work in the rock mass always leads to the violation of the natural balance and leads to the appearance of various natural or technical hazards.
