In response to the complex geological conditions of Yangquan Fifth Mine in Lu’an Chemical Group, which have resulted in the waste of a large amount of coal resources, the main reasons for the high loss rate of coal mines was analyzed. Targeted methods were proposed to improve coal mine resource recovery, including enhancing the foresight, accuracy, and effectiveness of geological prediction and forecasting, strictly formulating the management measures for top coal caving, reasonably adjusting the coal cutting and discharging processes, strengthening communication between functional departments and frontline production units, and enhancing supervision of coal transportation, washing and processing processes. By taking the above measures, the recovery of coal resources can improve greatly.

针对潞安化工集团阳泉五矿地质条件复杂造成大量煤炭资源浪费的现状,分析导致煤矿损失率偏高的主要原因。提出了提高煤矿资源回收的方法,包括提高地质预测预报的超前性、准确性和实效性,严格制定放顶煤管理办法,合理调节割煤、放煤工序,加强职能部门与一线生产单位的沟通与煤炭运输、洗选加工环节的监管力度等。通过采取以上措施,可极大提高煤炭资源的回收。
