Experimental study on subsidence law of the first mining face in the southern area of Shilawusu Mine

Based on the measured data from the surface subsidence observation station of the 1206A working face in the Shilaosu coal mine, in response to the small surface subsidence deformation caused by the mining of the large mining height working face under the Mesozoic thick sandstone in the western Ordos mining area, data sorting, curve drawing, parameter calculation, and comprehensive analysis were carried out to obtain the surface subsidence deformation law, angle parameters, and probability integration method predicted parameters caused by the mining of this working face. The characteristics and mechanisms of surface subsidence under the geological mining conditions were preliminarily analyzed, providing a scientific basis for the prediction and control of mining subsidence in this area in the future.
