摘要
针对东山煤矿煤层赋存和开采条件,介绍了15号煤层51519综放孤岛工作面顺槽超前支护选型研究,确定采用传统的超前支护方式:即采用单体液压支柱加金属顶梁(或工字钢)进行超前支护,论述了不采用超前液压支架的原因,为孤岛工作面综放开采超前支护提出一些有益的建议。
Based on the condition of No.15 coal seam of Dongshan Coal Mine,the advanced supports in coal roadway with isolated fully-mechanized top coal caving face was introduced,and the supports of the traditional way was determined,as well as the advanced supports by using individual hydraulic prop and metal headpiece（or h beam cap）.The reason of not using forepoling was elaborated,and some beneficial proposals to the support in advance was then put forward.
