Design and Result Study of Mine Pressure Observation Scheme
In view of the problem of mine pressure observation at the working face,by analyzing the rock strata distribution at the working face,a specific support scheme and mine pressure observation scheme are designed,and the rule of mine pressure is studied.Through field application,the monitoring results show that:During the mining work,the initial pressing step of the basic roof is 29.1 m,the average periodic pressing step is 19.8 m,the deformation of surrounding rock is small,the overall initial supporting force of the support is 23.5 MPa,indicating that the supporting effect of the working face is good.
