摘要
基于某煤矿2305综采工作面工程地质条件和开采技术条件,应用数值模拟(RFPA)和现场实测方法,深入研究了浅埋煤层开采后伪顶、直接顶和基本顶的破坏、运动规律,从而对指导、评价采场围岩控制提供理论依据。
Based on the engineering geological conditions and mining conditions of 2305 fully mechanized coal face,and by using the numerical simulation （RFPA,Rock Failure Process Analysis）and field measurement method,this paper makes deep analysis on the failure and movement laws of the false roof,immediate roof and basic roof after the mining of shallow seam,providing some theoretical bases for guiding and evaluating the control of surrounding rocks.
