摘要
基于某矿3113综采工作面过断层的各种因素,并考虑工作面推进速度与回采效率等综合指标,根据该工作面的地质情况最终进行沿底板推进过断层。通过采用数值模拟对3113工作面沿底板掘进进行模拟,模拟结果显示:沿底板掘进的设计方案能够有效控制顶底板的应力作用,并且有效控制了围岩的位移量,在安全通过断层的同时,又可以满足相应的工程经济需求。
Various factors based on the 3113 fully mechanized coal face passing fault in a mine,and consider the comprehensive indicators such as the working face propulsion speed and recovery efficiency.According to the geological conditions of the working face,working face mining along the bottom plate through the fault.The simulation of the 3113 working face along the bottom is simulated by numerical simulation,simulation of 3113 working face along the bottom plate by numerical simulation,the simulation results show:the design scheme along the bottom plate can effectively control the stress of the top and bottom plates,effectively control the displacement of the surrounding rock,while safely passing through the fault,it can meet the corresponding engineering economic needs.
