摘要
巨野井田龙固煤矿被巨厚松散层覆盖,具有埋藏深度大、开采煤层厚等特点,导水裂缝带发育高度高,威胁矿井的高效生产。结合工作面实际,综合采用FLAC和UDEC数值模拟软件得到导水裂缝带发育高度,以减少数值模拟中人为赋值误差影响;结合研发的多段封堵同步测漏系统对模拟结果进行了检验,并进行了误差分析与讨论。
Longgu coal mine of Juye mining field is covered by the thick loose bed, has many characteristics, such as an deep buried deep, mining thick coal seam, water cracks with high growth altitude, threatening the efficient production of mine. Combined with the actual working surface, using FLAC and UDEC numerical simulation software to get the water flowing fractured zone height, in order to reduce the impact of human error in numerical simulation of multi segment assignment; blocking synchronization leak detection system in combination with the research was tested on the simulation results, and the error is analyzed and discussed.
