摘要
针对同忻煤矿采区上层老空区存在积水的风险问题,通过理论经验公式计算和数值模拟验证相结合的手段对8204工作面上方导水裂隙高度开展研究,同时分析了工作面推进过程中导水裂隙发育规律,得出了同忻煤矿8204工作面上方导水裂隙高度模拟结果和经验公式高度一致的结论,为148.6~171.5m之间。通过现场实测验证,导水裂隙实际数值与理论计算相匹配,为现场矿井水害防治提供相应的技术支撑。
In view of the risk of ponding in the upper old goaf of Tongxin Coal Mine,the height of the water conducting fissure above the 8204 working face was studied by means of theoretical empirical formula calculation and numerical simulation verification,and the development law of the water conducting fissure during the advancing process of the working face was analyzed,and the conclusion that the height simulation result of the water conducting fissure above the 8204 working face of Tongxin Coal Mine was highly consistent with the empirical formula was drawn,148.6~171.5 m.According to the field measurement and verification,the actual value of the water diversion fissure matches the theoretical calculation,which provides the corresponding technical support for the prevention and control of mine water disaster on the site.
