分层固体充填工作面矿压显现规律对比分析研究

Comparative and analytic research of mine pressure behavior in layered solids filling face

国内外对建下分层固体充填开采厚煤层技术研究甚少,邢台矿在工广下成功实现了首个底层7608工作面充填开采,直接顶板为顶层充填开采后,形成约2.5 m厚的充填体假顶,通过矿压观测分析分层充填开采顶板活动规律,对比分析了分层固体充填开采工作面矿压显现规律,为工作面顶板管理、地表沉陷控制提供科学依据。

Study of layered solids filling face under buildings is rare at home and abroad, the first floor 7608 working face filling mining under buildings was completed, after filling mining the direct roof formed 2.5 m thick faked filling roof,layered solids filling face was analyzed by pressure observation, the mine pressure behavior in layered solids filling face was studied, which provided scientific reference for roof control and ground subsidence control.
