浅议建筑物下压煤宽条带开采技术

Discussion on mining wide strip mining under buildings

基于实测资料,深入分析开采沉陷率与开采宽深比之间的关系,建立非充分开采沉陷率与开采宽深比的玻兹曼函数关系,确定宽条带开采采动程度的临界值,为有效控制地表沉陷变形提供了可靠的技术依据,开采实践表明宽条带开采是可行的.

Based on the measured data,the relationships between the mining subsidence rate and the depth-depth ratio of mining were analyzed,and the Boltzmann function relationship between the non-full mining subsidence rate and the mining width-depth ratio was established to determine the criticality of the mining degree of wide strip mining.The value provided a reliable technical basis for effective control of surface subsidence deformation,and mining practice showed that wide strip mining was feasible.
