Research on gob-side entry retaning technology of Chahasu Coal Mine
In order to solve the difficulty of mining continuity and the waste of resources caused by roadway security coal pillar.Taking the No.31207 working face rubber conveying roadway of Chahau Coal Mine as the engineering background,the technical research along the gob-side entry retaning was carried out,and the reasonable strengthening support scheme of the roadway and the reserved roadway section above the filling material was determined,and the industrial practice was carried out.Through the analysis of the mine pressure monitoring results,the deformation law of the reserved roadway surrounding rock was obtained.The filling scheme adopted along gob-side entry retaning of No.31207 working face of Chahau Coal Mine is technically feasible and meets the requirements of engineering practice.
