潘一东矿软岩巷道底鼓机理与控制方法

Research on Mechanism and Control of Roadway Floor Heave in Panyidong Coal Mine

摘要: 底鼓难题是制约深部矿井安全生产的关键因素之一。基于固支岩梁力学分析,分析了影响巷道底鼓的主要因素,并针对性地提出了底鼓治理的系统控制法,结合潘一东矿巷道具体地质条件,通过数值模拟的方法确定了合理支护参数。

Abstract: Floor heave is one of the key factors hindering the safety production of deep mines.Based on the mechanics analysis of damaged rock beam,the main influence factors of floor heave are analyzed.Aiming to those,the system control method of floor heave has been proposed.Combined with specific geological conditions of Panyidong coal mine,the reasonable supporting parameters is determined by numerical simulation.
