| Abstract: | 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. |
