在改进矿井通风系统方面所需解决的最重要问题如下: 布置在几个水平同时作业工作面(包括采场和掘进头)的风量合理调节;分区式开采矿井中两台至六台主扇联合工作的合理运行;在矿井某些区段中的通风线路中按需要调节风量;而在其它区段进行最少风景调节的可能性;减少矿井风路的压差,尤其是采空区,使其漏风景减至最小,从而减少煤炭自燃的危险性。
The most important issues that need to be solved in improving the ventilation system of the mine are as follows: the air volume arranged at several levels of simultaneous working face (including the stope and the driving head) is reasonably adjusted; two to six main fans in the zone mining shaft are combined The reasonable operation of the work; adjust the air volume in the ventilation line in some sections of the mine as needed; and at least adjust the possibility of landscape adjustment in other sections; reduce the pressure difference of the air duct in the mine, especially the goaf, Leakage scenery to a minimum, thereby reducing the risk of spontaneous combustion of coal.
