| 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 opti- mized,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. |
