| Abstract: | 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. |
