桃山煤矿有可采煤层12层左右,层间距从几米到几十米不等,绝大部分煤层瓦斯含量高,透气性差,属高瓦斯矿井,近年来,针对桃山煤矿煤层情况在采区巷道布置方面做了很多调查研究工作,并在实践中进行了一些有益的尝试。1.因地制宜合理确定采区生产能力首先,高瓦斯矿井煤层群联合布置时,既要合理集中生产,采区内采掘工作面布置又不能过多,这样不仅可保证通风系统相对简单可靠。而且在发生事故时影响面较小,事故易于控制。其次高瓦斯煤层群 There are 12 layers of coal seam that can be taken out in Taoshan coal mine. The interval between layers is from a few meters to tens of meters. The vast majority of coal seams have high gas content and poor gas permeability, belonging to high gas mines. In recent years, Arrangements done a lot of research work, and in practice made some useful attempts. 1. Rationally determine the production capacity of the mining area according to the local conditions Firstly, when the coal seam group of high gas coal mines is jointly arranged, it is necessary to concentrate the production rationally and the layout of the mining face in the mining area can not be too large. This not only ensures that the ventilation system is relatively simple and reliable. And in the event of an accident less impact, easy to control the accident. Second, high gas coal seam group
