摘要
本文以鹤壁四矿斜井平巷地质条件为依据，采用ＡＤＩＮＡ有限元程序对巷道顶板高冒区分层充填进行了数值模拟研究，论证了分层充填的可行性，详细分析了分层充填的机理，模拟结果认为：巷道顶板高冒区分层充填不仅技术上可行、经济上合理，而且还有利于巷道围岩的长期稳定。
ased on the geological conditions of roadways underthe inclined shaft of Hebi Mine No. 4 , the paper carriedout the numerical simulation research on backfilling Thehigh roof fall cavities by layers, using ADINA finiteelem ent program; demonstrated the feasibility ofbackfilling by layers; and made an exhaustive analysis onits mechanism. The resultsindicate that the technique isnot only feasible and economized but alsofavorable for thelong-term stability of the rock surrounding the roadway.
