摘　　要：在单体工作面控顶设计中,当顶板厚度较大、分层情况不清楚时,如何估算划分各分层,为科学的顶板控制设计提供合理参数,实现科学管理采场顶板,对矿井生产安全及高产高效有极其重要的意义。文中采用的估算方法可以在类似地质条件下推广应用。During the course of roof- control of individual working face, when the thickness of main roof is great and the slice condition is illegibility, how to estimate main roof slice accurately which can supply logical parameters for the design of roof- control, carry out scientific management for stope roof, come into being high productivety and efficiency to mine safety. The main roof slice method adopted in text can be applied in the similar geological, condition.
