综采放顶煤工作面矿压显现规律的数值模拟研究

Numerical Analysis of Ground Pressure Phenomena in Longwall Face of Fully Mechanized Caving Mining

本文在现场实测资料和相似模拟试验的基础上，采用数值模拟方法，对三河尖煤矿７１３１工作面分层开采及放顶煤开采条件下上覆岩层的活动规律及矿压显现进行了系统的研究，并对不同开采条件下的覆岩结构特点进行了初步分析，所得结论在７１３１面的放顶煤开采中得到了验证，并对指导生产起到了积极的作用．

Based on in-situ observations and analoque maferial modelling, the finite element mothod was used to study the process of movement and destroying of the strata and ground pressune phenom ena in condition of slice mining and caving mining, and analysed the shructural charectenristics of immediate roof and main roof. Its conclusion rous proved in face7131, and played an rmportant role in caving mining method.
