矿山测量工作对煤炭资源开发应进行有效的监督检查作用。但多年来,在煤矿生产建设中监督检查作用被忽视,造成煤炭资源丢失严重(当然还有其它方面的原因)。据有关资料记载,煤炭年产量六亿吨,实际矿井回采率50%,采区回采率60%,工作面回采率也只达到70%左右,就需要动用12亿吨工业储量,资源浪费实在惊人。以鹤壁矿务局为例,从建局至1979年底,全局共产原煤6416.5万吨(测算产量)。如采区回采率按规定75%计算,合理损失应是2138.8万吨。实际采区回采率只有64.4%,损失煤炭资源3541.2万吨,多丢失1402.4万吨,相当于该局三年的产 Mine measurement work on the development of coal resources should be effective supervision and inspection role. However, over the years, the role of supervision and inspection in the construction of coal mines has been neglected, resulting in serious loss of coal resources (and of course other reasons). According to relevant information, annual output of 600 million tons of coal, the actual mine recovery rate of 50%, mining recovery rate of 60%, face recovery rate of only about 70%, you need to use 1.2 billion tons of industrial reserves, the waste of resources is amazing . Taking Hebi Mining Bureau as an example, from the establishment bureau to the end of 1979, the total output of 64,165,000 tons of coals (measured output). If the recovery rate mining area according to the provisions of 75%, a reasonable loss should be 21,388,000 tons. The actual mining area recovery rate of only 64.4%, 35.412 million tons of coal loss of resources, lost more than 14.424 million tons, equivalent to three years of production of the Bureau
