村庄下厚煤层二次条带开采参数分析

摘要

Combined with the actual situation of thick coal seam and large buried depth, a large, studied the second strip mining scheme using the key strata theory, numerical simulation of FLaC3D and"winsufer6.0"to analyze the ground movement and deformation of the building, determined the second strip mining parameter:the mining width 60m, leave width 80m, mining under the parameters, coal pillar stability, resource recovery rate is high.%结合某矿大埋深、厚煤层实际情况，对不同二次条带开采方案通过关键层理论分析、FLaC3D数值模拟和“winsufer6.0”地表移动变形研究，确定了建筑物下二次条带开采参数为：采宽60m，留宽80m，在此参数下开采，留设煤柱稳定性好，资源回收率高。
