Measurement and Analysis on Gas Resources and Gas Coal resource characteristics of small coal mines and their conformity questions

针对新华区内小煤矿井田位于平煤集团国有重点煤矿报废矿井或浅部报废水平的现状,将小煤矿井田划分为复采残采煤层井田和完整煤层井田两类。在分析小煤矿开采煤层赋存规律的基础上,研究了小煤矿采煤方法存在的问题和改进措施,指出小煤矿应推广壁式采煤方法,提高整体装备水平,才能保证矿井的安全生产。

Based on the actuality of minefields of small coal mines in Xinhua District located in abandoned coal mines or retired mining levels of major nation-owned coal mines of Pingdingshan Coal Group Company, China, the minefields of small coal mines are divided into two kinds of minefields with duplicate-mining seams and minefields with intact seams. The authors firstly analyzed the buried law of mining seams, existent questions and their countermeasures of coal winning method for small coal mines. It is coal winning method with wall style promoted and whole-equipment level improved for small coal mines that safety production of Chinese coal mines should be guaranteed.
