摘要
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。
Taoshan Colliery has about 12 minable seams, and the space between them is several meters or so. The gas content is high and the ventilation is poor in most of these, so they belong to high gas coal seams. In recent years, many research work were done to research the situation of the of the roadway layout of the mining area of high gas coal seams, and some useful attempts were carried out in the practice.
