Abstract

Abstract

The characters of methane emission at the working face No. 14201 in Shaqu Coal Mine were analyzed, the technical parameters to control methane by incline high-position alley pumping were optimized, and its control efficiency was investigated. The results showed that controlling methane in Shaqu Coal Mine by incline high-position alley pumping was very efficient, a great deal of high-concentration methane had been taken out with the pumping system, and this technique supplied a technical guarantee for safe production in the working face.
