对地质条件复杂和煤层赋存状况不稳定的突出煤层,在工程布置上很难使用正规采煤方法进行开采。街洞矿业公司茶山岭煤矿经过多年的实践和全面的对比、筛选,采用了“单引巷水平分层采煤”方法开采,使用这种采煤方法即能够很好的控制顶板,又能预防瓦斯突出,提高回采率。
In the case of the prominent coal seams, which have complex geological conditions and are unstable in occurrence of coal seams, it is very difficult to use regular coal mining methods for the project layout. After many years of practice and comprehensive comparison and screening, Dashanling Mine of Jiedong Mining Company has adopted the method of “horizontal stratified mining with single guideway” to exploit this method of coal mining, that is, the roof can be controlled well Can prevent gas outburst, improve recovery rate.
