通过对董庄煤矿3311工作面地表移动观测站成果的分析,论述了断层对开采移动变形参数的影响.由于3311工作面下方存在落差130m的董二正断层,并与该面开采下山移动角方向相反,致使下山开采影响范围缩小,下山移动角、边界角增大.
Through the analysis of the results of surface mobile observation station at 3311 working face of Dongzhuang Coal Mine, the influence of faults on the deformation parameters of mining is discussed.Due to the presence of the Dong Erzheng fault with a drop of 130m below the 3311 working face, As a result, the impact scope of down-hill mining narrowed, the down-hill moving angle and the boundary angle increased.
