摘　　要：针对何家塔煤矿50207工作面地面村庄房屋压煤问题,根据工作面地质采矿条件,进行了不同工况下采动影响计算。根据计算结果分析认为在全厚开采不能满足地面房屋居住安全运行的前提下,采用在工作面内部分限厚开采(2.4m)的优化开采方式,可实现地面重点关注房屋的居住安全。本文研究可为类似开采条件下压煤开采提供参考。Based on the geological and mining conditions of the 50207 working face of Hejiata Coal Mine,the mining impact calculation is carried out under different working conditions to address the problem of coal pressure in village houses on the ground.Based on the analysis of calculation results,it is believed that under the premise that full thickness mining cannot meet the safe operation of residential buildings on the ground,the optimized mining method of partially limiting thickness mining(2.4 m)within the working face can achieve a focus on residential safety of buildings on the ground.It can provide reference for coal mining under similar mining conditions.

关 键 词：村庄房屋 压煤开采 限厚开采 采动影响 优化设计
