Observation and Analysis of Mining Surface Subsidence in the 3202 Working Face of Nanyang Mine
In order to solve the problems of surface subsidence and mining damage caused by mining under the mountainous area of Nanyang Coal Mine,combined with the actual production and terrain characteristics of the mine,four observation lines are arranged above the 3202 working face.According to the actual measured data,the surface movement and deformation parameters are calculated,and the surface movement and deformation characteristics are analyzed to obtain the surface movement and deformation laws of mining under mountainous terrain conditions.The results show that the deformation law of the mining surface under the mountainous area of Nanyang Coal Mine is similar to that in the plain area as a whole.Due to the influence of surface slope and slope aspect,there are relatively significant differences in horizontal movement between mountainous areas and flat areas;Due to the influence of mountainous terrain,the range of surface movement is significantly larger than that of flat landforms.
