摘要
为解决长平矿现有端头支护技术中存在的各种缺陷,研制了适应长平矿综放工作面端头支护的液压支架,并在2313工作面进行应用试验。应用试验表明,该支架的支护能力强、支护面积大、不扎底、稳定性好,提高了端头的支护强度和效率。
In order to solve the defects existing in the existing end support technology in Changping Coal Mine,a hydraulic support suitable for end support in fully mechanized top coal caving face of Changping Coal Mine was developed and tested in the 2313 working face. The application test shows that the support has strong support capacity, large support area, no bottom, good stability, and improves the support strength and efficiency of the end.
