摘要 通过对矿井构造地质条件、水文地质条件、覆岩结构类型、基岩风化带特征的分析,对13-1煤层原80m防水煤柱进行了重新留设,并给出了不同情况下防水煤柱的计算公式,且满足生产实际需要,这对进一步回收煤炭资源、提高经济效益有重要意义。 The former coal column of 80 metres thick at seam 13-1 is renewed after analysis has been made on the structural geological condition,hydrogeological condition,the cover rock's textural types and bedrock's weathing character of shafts.Further,a calculation formula is given for the set-up of a water-proof coal column.It is important for the recovery of coal resources and rather the increase of economic efficiency.
