摘 要: 为研究煤层开采深度对煤与瓦斯突出的影响,以平顶山矿区八矿戊9-10、己15两煤层为例,基于矿区地应力测量、岩体应力状态数值模拟和矿区地质动力区划等研究工作,从能量的角度分析模型区域内两煤层煤岩体内的弹性潜能差异,绘出两煤层顶板弹性潜能分布等值线图,计算出戊9-10和己15煤层煤岩体的弹性潜能值。分析得出深部己15煤层煤岩体聚集的弹性潜能较浅部戊9-10煤层大很多,煤与瓦斯突出发生的可能性增加、强度增大,进而可得出在同一井田范围内不同的煤层开采深度对煤与瓦斯突出的影响。
关 键 词: 采矿工程;开采深度;煤与瓦斯突出;弹性潜能

Abstract: To study the effect of mining depth to coal and gas outburst, this paper takes two coal seams of J15 and W9-10 in Pingdingshan mine as examples, and bases on the research work such as field stress measurement, numerical simulation of rock stress, geodynamic zoning in mining area, and analyzes the difference of elastic potential energy between two seams in model region from the point of energy, then provides distribution contour of elastic potential energy of two seams roof, and calculates the elastic potential energy of two seams. It concludes that the elastic potential energy of deeper J15 coal seam is much bigger than that of shallow W9-10 coal seam, and results in the increase of possibility and strength of coal and gas outburst, therefore getting the relationship of influence between mining depth and coal and gas outburst.
Key words: mining engineering; mining depth; coal and gas outburst; elastic potential energy
