- W2378175884 abstract "Aiming at the problem that the highly concentrated mining layout in Panyi mine,were resulted in a substantial increase requirement for air volume in the west third district,and it high negative pressure in the central air mine fan,an adjustment and optimization program of ventilation system was proposed.Combining with the future development plan of the mine,the methods to speed up the second level tunneling and to prepare the pillar working face in advance were put forward,resistance reduction measures of inlet segment and return airway in the west third district.Simulation results showed that: taking measures from the inlet segment and return airways in the same time and increasing the tunnel across within the mining area can effectively improve the situation of higher ventilation resistance in west third district,and the fan negative pressure main can be reduced to a reasonable range." @default.
