首采综放工作面停采技术研究

Study on Stop Mining Technology of the First Fully Mechanized Caving Face

为解决特厚煤层首采综放工作面停采难题,以晋能控股煤业集团虎龙沟矿首个综放工作面为工程地质背景,通过对超前压力和周期来压的监测分析,总结其平均来压步距和来压强度,有效避开周期来压影响,确定不放煤距离及末采阶段合理停采位置,并制定科学停采支护方案,实现首采综放工作面安全高效停采。

In order to solve the stop mining problem of the first fully mechanized caving face in the extra-thick coal seam,taking the first fully mechanized caving face in Hulonggou Mine of Jinneng Coal Industry Group as the engineering geological background,through the monitoring and analysis of the advance pressure and periodic weighting,the average weighting step and weighting strength are summarized,to effectively avoid the impact of the weekly weighting,to determine the non-caving distance and the reasonable stop mining position in the final mining stage,and to formulate a scientific stop mining support plan,realize safe and efficient stop mining of the first fully mechanized caving face.
