Abstract: in order to define the drainage technology content of surace well n the mining stable area ofcoal mine,based on a theoreical studyanalogous analysand site test.the surace well ype and techrcal features in the mine area were deeply analyzed.The paper pointed out that the drainage cech nogy of the coabed methane surtace well in the mining stable area would cutweigh the fill development of caled methane resouces.The technology would moreconcern the evaluaton on the coabed methane resource volume before the production conducted and the study and appication of friling and completron fechnicue in the broken strata. The key technology would include the coalbed nethane resource evaluation optimized des gn of the surface well structure, optinized design of the w el ocation selecion and theoptimized design of the drling and comletion technicue. Dilferent certain analysis should be conducted on the applicaion contions to protect the coalbed methanemining effect.The site drainage test in Chengzhuang Mine of Shanxi Jincheng Anthracite Mining Group showed that with the application of the coalbed methane surface drainage technology of the nining stable area.,the drainage gas volume fracion of the surtace well vas about 40%.the dally drained pure volume was 3 120 m-3 and te suitability of the surface well drainage technology in the mining stable area was approved.
