综采轻型放顶煤工艺探讨

Discussion on Light Caving Coal Technique in Fully Mechanized Mining

根据杨村煤矿煤层赋存情况及生产实践,对杨村矿综采轻型放顶煤工艺的采放比、放煤步距、放煤顺序进行探讨,介绍应用此工艺后取得的社会和经济效果,值得今后在一些复杂难采厚煤层矿井中进行推广应用。

According to the situation of coal seam hosting and production practice about the Yangcun coal, the author who introduced the Socio-economic effect after the technique diseussioned the caving ratio.coal caving distance and caving order on light caving coal technique in fully mechanized mining about the Yangcun coal. It could be promoted in the in high seam face of trouble mining.
