摘要
分析了煤质管理中存在的煤质管理体系不完善、原煤及商品煤管控不足等问题,针对济宁二号矿井地质条件复杂、煤炭质量不稳定的情况,提出了加强煤质管理的主要措施:完善质量管理体系;加大井下原煤质量管理力度;加强工作面质量控制力度,合理搭配开采,力保原煤质量稳定;开展井下大杂物专项整治和杂物事故教育活动;强化对商品煤质量动态管控;狠抓商品煤水分考核力度;强化外购煤配煤管理;开展“三零”工程;优化产品结构等。通过以上措施,降低了原煤和精煤含杂率,商品煤质量不断提高,树立了良好的质量品牌,实现了提质增效。
This paper analyzed the problems existing in coal quality management,such as the imperfect coal quality management system and the insufficient control of run-of-mine coal and commercial coal.Based on the situation of complex geological conditions in the mine shaft and unstable coal quality,this paper proposed the main measures of strengthening the coal quality management:improving the quality management system;strengthening the quality management of run-of-mine coal;strengthening the quality control of working surface to ensure the stable quality of raw coal with rational exploitation,taking educational activities of Special Rectification of Debris;strengthening the dynamic control of the quality of commercial coal,vigorously reinforcing assessment of the moisture content of commercial coal,paying close attention to the management of outsourcing coal blending,carrying out the“three zero”project,optimizing product structure,etc.Through the above measures,impurity content of run-of-mine coal and clean coal is reduced,quality of commercial coal is enhanced,a good brand of quality is established,quality and efficiency get improved.
