我国东部地区矿产资源形势严峻,多个企业反采以往遗漏的煤层,创造经济效益。然而,以往的上行顺序采煤判别方法,没有对裂隙漏风做详尽的研究,使得判别方法不合理。分析并介绍了煤层反采过程中的裂隙漏风问题,提出了以往判别法中的不合理之处,并对其进行了初步修改。对于现有煤矿存在的煤层反采裂隙漏风问题提出了系统的解决方法,为煤层反采工作起到一定的指导作用。
The situation of mineral resources in the eastern part of our country is grim. Many enterprises oppose the previously missed coal seams and create economic benefits. However, in the past, the coal mining sequence in the ascending order did not make exhaustive research on the fissure air leakage, making the discrimination method unreasonable. This paper analyzes and introduces the problem of fissure air leakage in the coal seam anti-mining process, puts forward the unreasonable points in the previous discriminant method and makes some preliminary revisions. A systematic solution is put forward for the existing coal seam anti-mining and fissure air leakage problems, which will play a guiding role in the coal seam anti-mining work.
