Gas accumulation at upper corner angle of comprehensive prevention and control of fully mechanized coal face in the process of tunnel ventilation
Abstract：Fully mechanized coal face upper corner gas accumulation and treatment at home and abroad has been the key prob- lem, for gas accumulation in the upper corner of treatment, we adopted comprehensive prevention technology that techmoloy tun- nel ventilation and drainage hole technique, and＇at dawn in 1210 working face of success. This paper mainly on the process of lane ventilation method implementation are introduced in detail, and explains its practical application in the success of technology and technical conclusions.
