Roof-cutting Pressure Relief Technology of Coal Pillars in Main Roadway of 10105 Working Face of Hongyan Coal Mine
In view of the problem of the impact of the first mining area of 10105 working face of Hongyan Coal Mine affecting the downhill track and the water tank in the mining area,the mechanism of abnormal strata behaviors were clarified through analysis,and a reasonable and feasible targeted roof-cutting pressure relief scheme was formulated accordingly,which can guide the underground construction.
