马头门巷道变形监测及破坏原因分析

Analysis of Deformation Monitoring and Destruction Reasons about the Ingate Roadway

马头门是煤矿生产的咽喉部位,因其具有断面大、周围巷道多、应力集中明显等特性,使得马头门巷道的支护问题成为影响矿井安全高效生产的瓶颈。本文以羊东矿为工程背景,采用现场观测、理论分析的方法,首先分析原有支护体系下马头门巷道的变形规律;其次,结合现场实际理论分析马头门巷道变形破坏的主要原因,为羊东矿马头门巷道的变形治理提供科学的理论依据。

Ingate is the throat site of coal mine production,because of the characteristics of large section,more roadway around and the obvious stress concentration,the support problem of the Horsehead tunnel becomes the bottleneck of the safe and efficient production of the mine.Based on the engineering background of Yangdong coal mine,using the method of fieldobservation and theoretical analysis,this paper analyzed the deformation law of ingate roadway under the original support system,and analyzed the destruction reasons of ingate roadway deformation law of ingate roadway combined with the actual situation,to provide a scientific theory basis for the deformation control of ingate roadway in Yangdong coal mine.
