摘要
Abstract
Zhulinshan Coal Mine adopts a"one well,one side"production organization method.In order to effectively avoid the problem of large deformation of the surrounding rock of the channel,the traditional construction process of the withdrawal channel in this mine is to use a roadheader for on-site excavation.This process has the disadvantages of slow construction speed and long construction period,which seriously delays the progress of equipment withdrawal and affects the normal continuation of mining and excavation.In view of this,research is conducted on the optimization of the construction process for the withdrawal channel.Based on a specific analysis of the shortcomings of traditional construction methods,optimization principles are proposed;through targeted technical analysis and reference to currently relatively mature materials and processes,an optimized construction process of"grouting and roof side reinforcement+high-strength flexible mesh+coal mining machine coal cutting"is proposed,and the construction parameters are confirmed.In the application of the withdrawal channel construction in the 1403 working face,the construction period is shortened by 11 days,creating favorable conditions for the safe and rapid withdrawal of equipment in the fully mechanized mining face.关键词
