| Abstract: | A measuring method on ground discontinuous deformation due to steeply inclined coal seam mining is put forward. By applying finite element method, analysis of main influenced factors to surface discontinuous deformation on condition of interlayer weak planes are made. A series of calculation formula and method on discontinuous deformation have been derived under considering the aspects of underground mining influence, position and width of weak plane, and mechanical property of weak plane medium. Analysis of some examples verifies that the set up calculation method is easy to apply and good results have been obtained. The method provides a new way for calculating ground non continuous deformation. |
| Keywords: | steep seam mining interlayer weak plane discontinuous deformation calculation method |
