摘　　要：针对综合机械化采煤提高开采上限工作面在大倾角地质条件下因顶板管理不利,造成回采过程中发生溃水、溃砂事故。通过分析地质和煤层赋存条件,选择综采、综放综合采煤方法,采取分段上网,设备状态控制,顶板破碎区超前管控等一系列工程措施的现场落实,能够有效的控制顶板下沉、开裂,避免顶板事故的发生。现场实践证明合理的开采方式及顶板控制方法能够有效控制顶板非均衡破坏和矿压显现异常现象,提高大倾角条件下提高开采上限工作面的回采效率。In view of the upper limit of comprehensive mechanized coal mining to improve mining working face under the geological condition of large dip Angle for roof control, cause collapse, crushing sand water accident in the process of mining. By analyzing the geology and coal seam occurrence condition, the choice and fully mechanized coal mining method, to block access to the Internet, control equipment status, roof and broken zone controls in advance a series of measures such as on-site implementation, can effectively control the roof subsidence, craze, to prevent roof accidents. Field practice proved rational mining method and roof control method can effectively control abnormally pressure roof destruction of disequilibrium and phenomenon, improve the improve the upper limit of mining working face under the condition of large dip Angle mining efficiency.
