摘 要:由于缺少实际案例,对如何准确计算关闭矿井淹没式充水储水空间在国内外研究相对较少。结合徐州东部矿区权台煤矿关闭过程,通过超前计算常规储水空间,分步关停排水系统,加强充水过程水位监测,系统开展了关闭矿井淹没式充水储水空间计算研究,发现高承压条件下淹没式矿井充水实际储水空间较常规计算采空区储水空间存在较大差异,创新性提出了淹没式矿井充水比例系数的概念,并经过计算得出1.3的经验值,丰富了煤矿关井后防治水实践研究,对类似条件下关闭矿井储水空间计算具有借鉴意义。Due to the lack of practical cases,there are relatively few studies at home and abroad on how to accurately calculate and close the submerged water-filled water storage space in mines.Combined with the closing process of the Quantai Coal Mine in the eastern mining area of Xuzhou,by calculating the conventional water storage space in advance,shutting down the drainage system step by step,and strengthening the monitoring of the water level during the water filling process,the system carried out a study on the calculation of the flooded water storage space in the closed mine.The actual water storage space of submerged mine water filling under pressure conditions was quite different from the conventional calculation of the water storage space of goaf.The concept of water filling proportional coefficient of submerged mine mine was innovatively proposed,and the empirical value of 1.3 was obtained through calculation.It enriched the practical research on water prevention and control after coal mines are closed,and had reference significance for the calculation of water storage space in closed mines under similar conditions.
关 键 词:关闭煤矿 淹没式充水 储水空间 采空区积水充水系数 淹没式矿井充水比例系数
