Abstract: Based on extraction data from released coal-bed methane surface well in Huainan mine area, according to the GuQiao coal mine stratum condition for prototype, we do experimentation of Similar Material Simulation, combine the results of experiment, we discuss the stability problem of coal-bed methane surface well, educe the destroy mechanism of released coal-bed methane surface well in Huainan mine area. The findings indicate that coal-bed methane surface wells are easily destroyed in interface of loose strata and the bedrock and upper hard lower soft of bedrock. Well location should be closed with the place of inlet lane and return airway, far from working face, and the peak value of relative horizontal displacement between working face and wind lane. It’s conducive to CBM well location, improve the extraction results.
