针对某矿8号煤层和9号煤层近距离煤层上行开采的问题,采用理论分析和数值模拟相结合方法开展其可行性评价.研究结果表明,8号煤层和9号煤层近距煤层上行开采的技术方案切实可行,采取快速推进、人工假顶、高额定工作阻力支撑掩护式支架等技术措施,可有效改善8号煤层的下沉状态,实现8号煤层安全高产高效回采,取得了良好技术经济效果和社会经济效益,推动了近距离煤层上行开采技术的发展.“,”In view of ascending mining problem to near distance coal seam of both the No.8 and No.9 coal seam, theoretical analysis and numerical simulation were applied to carry out its feasibility evaluation. The results showed that technical proposal of ascending mining for No.8 and No.9 coal seam was feasible. Taking technology measures such as the rapid advance, artificial roof, chock-shield hydraulic support of high rated working resistance and so on, can effectively improve the subsidence of theNo.8 coal seam, so as to maintain the coal 8th continuous bending, achieving high yield and high efficiency coal mining safety of No.8 coal seam. The application had achieved good technology the economic effect and social economic benefits, promoted the development of close distance coal seam mining technology.
