1. Actuality of theme One of the problems of ventilation mine - air leaks that occur through the ventilation facilities in the mine and on the surface, caving, broken pillars. These reduce the flow of air to the areas of consumption, may be violating the ventilation shaft. To compensate for the increased flow of air leakage into the shaft. Fighting them is carried out by sealing the ventilation facilities, insulation developed spaces, using field workings of rational schemes of ventilation, reduced obscheshahtnoy depression. An important task of the ventilation shaft - ensuring the safety of people in case of accidents (fire, explosion of gas and dust, sudden coal and gas), and their elimination. Requirements for the ventilation shaft in case of emergencies: preventing the spread of toxic gases through the mine; fast and reliable reverse ventilation jets; a warning of hazardous concentrations of explosive gases and others. Modes of ventilation shafts in case of emergencies: proper ventilation; increase or decrease the air flow; cessation of ventilation; reversal.
2. The purpose and objectives of the study, expected results The main objectives of the study:
1. Conduct a simulation perekrepleniya sites with great resistance by the program. 2.Rate increase air flow in the mine after perekrepleniya and if the value exceeds 10% (error change of air flow) is to consider reducing the value of external and internal leaks.3.Characteristics of mine Geographically mine is located in the Mining district of Makeyevka Donetsk region of Ukraine. Industrially mine subordinated SE "Makeevugol." Closest to the mine district center - the city of Makeyevka, the regional center - the city of Donetsk. The structure of the mine "Cold Beam" is now included mine number 3 and "South." These shafts are combined into a single ventilation system. Stocks of coal within the technical limits of the mine "South" developed. Therefore, the ventilation shaft "South" are used for the issuance of the rock and ventilation openings of the northern and eastern wings. Mine number 3 is located 7 km south of the city of Makeyevka of Donetsk region and within the local Mining District of the city of Makeyevka. With the nearest villages and the city of Makeyevka Mine associated asphalt roads. Electricity is provided by the regional mine substation "Cold Beam" -35 "new" grid "Donbasenergo."
4. Ventilation shafts The mine is ventilated by means of two fan installations of main ventilation: WDC-31.5 on the skip shaft mine "South" and water-30M on the skip shaft mine №3. The method of ventilation - suction, ventilation scheme - combined. Fresh air enters the mine cage shaft of mine №3, then the inclined conveyor and auxiliary crosscut on the reservoir enters the horizon of 750 m in the reservoir development. Outgoing air stream is derived in two ways: on the ventilation crosscut inclined to skip shaft №3 and on the northern horizon ventilation crosscut of 750 m on the skip shaft "Southern." Estimated amount of air to ventilate the mine is 7858 m3 / min, in fact, the mine enters 9273 m3 / min of air. Estimated flow of air is provided on the shaft 118.4%. The absolute volume of gas shaft 31.28 m3 / min; relative - 54.02 m3 / t.s.d. Ventilation in production areas is carried out on the circuit with tap vozvratnotochnoy outgoing air flow in the goaf. To reduce methane at excavation sites carried degassing reservoir satellite and located in the roof of the reservoir and reservoir satellite located in the soil formation. For the removal of methane-air mixture in mines laid pipes with a diameter of 200 - 300 mm. Surface decontamination plant, located in the industrial area of ??the mine №3, equipped with three vacuum pumps HB-50. Degassing efficiency of 40%. Captured methane degassing means used in the mine boiler house.
5.Calculation of the amount of air required to separately ventilated development workings, cameras and supported workings. 
Internal leakage beyond the excavation sites, external suction.
