| Abstract: | According to site investigation of longwall face, adopting statistical regressiion and theoretical analysis, the computing method of roof pressure on divided support in Jixi Mining Bureau is studied and analyzed. The roof pressure pressed by the main roof stratum on the immediate roof is established by using the ratio of immediate roof thickness to mining height.A practical computing method to figure out the roof pressure is concluded at last and put into practice in Jixi area. |
