轿子山煤矿新井由于煤层较薄,采高较低,综采工作面的顶板属于极坚硬类别,选择在轿子山煤矿新井9106回风巷实施沿空留巷。该沿空留巷主要方式为采用造价低廉的木垛支护采空区侧顶板,维护预留巷道作为下一个工作面切眼使用。经过后期观察,采用木垛支护沿空留巷技术在轿子山煤矿新井薄煤层综采工作面取得了成功,为轿子山煤矿创造了巨大的效益。 Due to the thin coal seam and the low mining height, the new roof of the Jiaozishan Coal Mine has a very hard roof. The roof of the fully mechanized coal mining face belongs to a very hard category. The main method of gob-side entry retaining is the use of a low cost wooden shingle support gob-side roof, maintenance of reserved roadway as the next face cut. After the late observation, the use of woodpulp retaining gob-side entry retaining technology has succeeded in the fully mechanized mining face of the new shaft and the thin coal seam in the Jiaozishan Coal Mine, creating tremendous benefits for the Jiaozishan Coal Mine.
