摘 要:在分析近距离煤层群上行开采机理与主要影响因素的基础上,针对传统煤层群上行开采判别方法的局限性,对上位煤层的覆岩状况与上行开采的关系进行了阐述.给出了平顶山四矿近距离薄煤层群和内蒙古酸刺沟煤矿厚煤层群上行开采的工程实例,并确定了上行开采的关键技术措施.理论分析、数值模拟和工程实践证明,上位煤层覆岩岩性及结构对上行开采有影响.研究成果扩大了近距离煤层群上行开采的应用范围,对衰老矿区遗留煤炭资源的回收和特大型现代化新型矿区的开发规划及西部矿区的生态环境保护都具有重要的意义.图1,表3,参9.To solve the traditional judgments difficulties of the ascending mining, the relationship between the ascending mining and the overlying strata of upper coal seam was expatiated, based on the analysis of the mechanism of ascending mining and the traditional main factors that influence it. The industrial test of ascending mining of the near distance thin coal seam group in Pingdingshan No.4 coal mine and the near distance thick coal seam group in Suancigou coal mine, and the key technical measures of ascending mining were put forward. Theoretic analysis, numerical simulation and industrial test proved that the lithology and its structure of overlying strata of the upper coal seam have influence to the feasibility of ascending mining. The study achievements broaden the application area of ascending mining. It is important to increase the recovery ratio of leaving behind coal resources in the old mine area and layout the modem oversize mine area and protect the environment in the western mine area. lfigs., 3tabs., 9refs.
