Research Review and Advance on Shallow Buried Coal Seam Mining Pressure

Abstract:

In order to research the law of mine pressure and roof control in shallow buried coal seam, based on a comprehensive summary of mine pressure theory, technology application, engineering practice, summarized research results and status, analyzed research shortage, proposed research proposals. The results show that:1“short masonry beam” and “step beam” structure mechanical model and “key stratum in shallow seam theory” has provided theory basis for coal seam roof control shallow guidance. 2Rock and soil (bedrock and alluvium) coupling mechanism, loose layer dynamic structure theory," coal mining, water retention, ecology conservation, subsidence control" optimized portfolio on management theory and technical system of is the required research direction. 3Sichuan, Yunnan, Guizhou, representative of southwest mountainous shallow buried coal seam mining pressure research is conducive to development of mining pressure theory system.
