Application of Two-leg Hydraulic Support with Top Coal Caving Based on Relationship between Support and Surrounding Rock in Fully Mechanized Top Coal Caving Mining
On the basis of analyzing feature of relationship between support and surrounding rock in fully mechanized top coal caving mining, the loading character and problems of the four-leg chock-shield hydraulic support with top coal caving which the pressure at front and rear supports are not even, the utilization rate of working pressure at the rear leg is low and the support frame is broken easily at present, this paper analyzed the structure character and dynamic stress feature of a new support type of two-leg hydraulic with top coal caving support, its loading law and change one of support loading influenced by caving procedure during industrial test, its adaptation, and prospects the future developing trend of the top coal caving mining technology.
fully mechanized top coal caving two-leg hydraulic support with top coal caving relationship between the support and surrounding rock support type
