矿山采空区资源富集规律及采动压力研究

Study on resource enrichment law and mining pressure in Goaf

我国分布着很多含有小尺寸采空区或倾斜采空区的矿井。本文主要研究采空区易燃气体赋存状态、运移规律和地层渗透率的影响因素,并研究了围岩应力与矿石破坏机制,总结出了采空区易燃气体富集规律,并对采动压力开展研究,进而为研究卸压情况下易燃气体沿不同方向的流动规律提供理论指导。

There are many mines with small-size goaf or inclined goaf in China.This paper mainly studies the occurrence state,migration law and influencing factors of formation permeability of flammable gas in goaf,and studies the surrounding rock stress and ore failure mechanism,summarizes the enrichment law of flammable gas in goaf,and studies the mining pressure,so as to provide theoretical guidance for studying the flow law of flammable gas in different directions under pressure relief.
