【摘要】:针对哈拉沟煤矿22206综采工作面采空区和22205工作面采空区的高压氮气导通,造成回风隅角和回风巷的氧气浓度偏低,不利于安全生产的问题,通过变U型通风方式为Y型通风,彻底解决了回风隅角和回风巷氧气浓度低的问题。
[Abstract]:In view of the high pressure nitrogen conduction in the goaf and the 22205 working face in the 22206 fully mechanized coal mining face in haralin coal mine, the oxygen concentration in the return air corner and the return air lane is low, which is not conducive to the safety of production. The problem of low oxygen concentration in the corner of the return air and the return air lane is solved thoroughly by the change of the U ventilation mode to the Y type ventilation.
