摘要
采场覆岩三带高度的准确计算对生产实践具有重要意义。采用理论计算、RFPA数值模拟和现场实测的方法,研究了野川煤矿3号煤层综放开采条件下覆岩三带的发育高度,对理论计算、数值模拟及现场实测结果进行对比分析,结果表明,《建筑物、水体、铁路及主要井巷煤柱留设与压煤开采规程》的公式不适用于综放开采覆岩两带高度的计算,而采用经验公式的计算结果比较符合。
Accurate calculation of ＂ three-zone＂ height of overlying strata in mining area has great significance to coal mine work.In this paper,by using theoretical calculation,combining with RFPA numerical simulation and field measurement,the ＂ three-zone＂ development height of overlying strata under fully-mechanized top coal caving in 3#coal seam of Yechuan Coal Mine was researched.By comparative analyzing the results of theoretical calculation,numerical simulation,it drew a conclusion that the formula in the current regulation was not adaptable,however,the experiential formula was adaptable for the ＂ two-zone＂ development height of overlying strata under fully-mechanized caving.
