摘要
条带开采条件下巷道的变形规律非常复杂 ,其变形规律同非条带开采的巷道有较大的差别。通过某矿一条条带开采巷道的实测及模拟实验结果 ,采用岩层移动理论———关键层理论及一般矿压理论———顶板回转理论等 ,对其变形进行了分析研究 ,得到了一些以前未曾揭示的规律 ,可供类似条件下的巷道支护参考。
The deformation law of roadways under the condition of mining in strips is very complicated and much different from those under condition of non-strip mining. Based on results of actual survey and simulation experiment done to a roadway of strip mining in a certain coalmine,the deformation of it is analyzed and researched in the paper with such theories as strata movement theory,key strata theory,strata control theory and roof movement theory etc.,and some laws that have never been revealed before are obtained,which will provide valuable reference for roadway support under similar conditions.
