Abstract: In complicated geological conditions of more fault structure, under its influence, the fully mechanized coal face irregular arrangement, stoping process is also accompanied by safety, technical and economic issues, such as the efficiency of full mechanized face equipment is restricted, advance speed slow, security risks, efficiency of mining and recovery coefficient low. Chensilou coal mine 21004 fully mechanized working face by primary slope adjustment and through a variety of over-fault technology to ensure the production of complex geological conditions, and has accumulated rich safety production experience. Based on analysis and summary the technology of stoping process , and provides a good reference example under the similar condition of coal bed mining, with a high reference value.

Key words: complicated geological conditions, fully-mechanized face, slope adjustment, passed through fault, technology
