Study on the Application of Gob Drainage Pipe Technology in Gas Controlling at the Upper Corner of Working Face with U Type Ventilation System

Abstract:

This paper takes the fully mechanized face of Yuecheng mine 1302 for example, Yuecheng mine belongs to Jincheng Mining Group in Shanxi. It talks about the gas emission law and governance principles which happen in the gob with U Type ventilation. The research proves that, with laying two goaf pipelines in the ventilation roadway, one inserts into the upper corner to drainage and the other one embeds into the gob to drainage, it can effectively prevent the gas in the gob from emitting, and can eliminate the gas accumulation at the upper corner in the working face and ensure the safety of production in the working face.
