Abstract:
In order to promote the safe and efficient production of high gas working face, applying airbags to fill the upper corner in fully mechanized mining face during the mining time is proposed. The 66310 protective layer at fully mechanized mining face of Xinzhuangzi Coal Mine is taken as an engineering example, the technology of applying airbags quickly to fill in upper corner is introduced, applying airbags quickly filling method effectively promoted the safe and efficient production of 66310 face. The results show that: compared with the method of double anti-bagged coal gangue filling the upper corner, airbags filling is of easy to move, low investment, greatly reducing the labor intensity of workers, improving the progress of the face. The filling airbags is of good sealing performance, safe blocking effect is obvious, and it has a good promotion value.
