| Abstract: | According to the distribution of industrial square, shaft and other buildings(structures) in Qingcheng Coal Mine of Shengtianbaodi, Shanxi Province, the reserved range of protective coal pillar in 15101 working face was determined. At the same time, the surface subsidence was calculated by probability integral method, and the maximum subsidence of shaft and other buildings(structures) was calculated. The corresponding protective measures were put forward for the buildings(structures) with great influence. |
