摘要
以铜川矿务局陈家山煤矿为例,分析了特厚煤层分层开采时,尽管台账上矿井“三量”符合国家规定,但生产接续十分紧张的原因;提出了新的“三量”可采期的确定方法。
For instance of Chenjiashan Coal Mine,it was difficult to recover the developed coalreserves,the prepared coal reserves and the extraction coal reserves successively as the special thick coalseam was mined in parts though the quantities of the above three kinds of coal reserves accorded with thedemands of rational recoverable time.And a new method for determining the rational recoverable time of thethree coal quantities was reported.
