摘要
结合周源山煤矿24采区上覆岩层实际情况,依据概率积分法原理,采用开采沉陷预计系统,得到了周源山煤矿24采区在同采一、四煤的情况下,地表以及地表重点保护建筑物(焦化厂、矸石发电厂和张家珑水库等)的最大下沉值、最大曲率、最大水平移动、最大水平变形、最大倾斜值和地表各建筑物的损伤等级,提出了相应的建筑防护措施。
Combined with the actual situation of the overlying strata in 24th mining area of Zhouyuanshan coal mine and based on theory of probability integral method, by using mining subsidence prediction system, the maximum subsidence value, curvature, horizontal displacement, inclination and the building damage grade of ground and surface key preteetion building （coking plant, gangue power plant and Zhangjialong reservoir） were obtained under the condition of simultaneously mining No. 1 and No. 4 coal in 24th mining area of Zhouyuanshan mine. And building protective measures are proposed.
