长平公司制定完善的大倾角大采高破碎顶板工作面回采方案，采用磨机头、单向顶溜、打戗柱、工作面伪倾斜推进等多种措施，解决了4314大采高工作面因机头机尾高差过大、工作面顶板伪顶破碎严重等因素造成的刮板输送机前窜、支架歪斜度超标、支架挤架咬架等难题，为工作面的顺利回采提供了可靠保障。
長平公司製定完善的大傾角大採高破碎頂闆工作麵迴採方案，採用磨機頭、單嚮頂霤、打戧柱、工作麵偽傾斜推進等多種措施，解決瞭4314大採高工作麵因機頭機尾高差過大、工作麵頂闆偽頂破碎嚴重等因素造成的颳闆輸送機前竄、支架歪斜度超標、支架擠架咬架等難題，為工作麵的順利迴採提供瞭可靠保障。
장평공사제정완선적대경각대채고파쇄정판공작면회채방안，채용마궤두、단향정류、타창주、공작면위경사추진등다충조시，해결료4314대채고공작면인궤두궤미고차과대、공작면정판위정파쇄엄중등인소조성적괄판수송궤전찬、지가왜사도초표、지가제가교가등난제，위공작면적순리회채제공료가고보장。
Changping Company develop the perfect mining scheme of broken roof working face with large dip angle and large mining high, by moving the head of scraper conveyer, pushing the scraper conveyer in one-way, playing a side support, and mining along the inclined direction, solve the problem of scraper conveyor slipping forward, the crowding and slanting support and the exceed standard of bracket skewness caused by the broken false roof of 4314 working face with large mining height, provides reliable guarantee for working face successfully mining.
