我矿近年来所采取的防灭火主要措施是:黄泥灌浆、均压灭火等方法。随着煤炭工业的不断发展,机械化程度的提高,回采工作面走向长度和工作面的长度则必须相应地加大,以适应生产的需要。为此,鉴于我矿带有中巷的回采工作面比无中巷的回采工作面发火多的教训,又由于回采工作面的长度及其走向长度的加大,可采期则延长,这是造成火灾隐患多之故。于是,我们在二井071N第二分层带有中巷的回采工作面采用E型通风方式进行预防火灾试验。经过一年多的生产实践,该工作面从始至终,共采出煤炭227,601吨,没有自燃发火,收到了可喜的效果,达到了预期的目的。 In recent years, mine mine fire prevention measures taken are: yellow mud grouting, pressure equalization and other methods. With the continuous development of the coal industry and the improvement of mechanization, the length of the working face and the length of the working face must be correspondingly increased to meet the needs of production. In view of this, in view of my mine with middle lane of the mining face than the middle of the backfill face flaming more lessons, but also because of the mining face length and the direction of the increase in length, mining period is extended, which is Causing many fire hazards. As a result, we used the E-type ventilation method to prevent fire test in the secondary strata with the middle lane of No.2 Well 071N. After more than a year of production practice, the face from start to finish, a total of 227,601 tons of coal mining, no spontaneous combustion, received gratifying results, to achieve the desired purpose.
