耿村矿于去年八月开始使用SCF—6型除尘风机,碰到不少问题,走了一些弯路,也取得了一定成果。 一、试用除尘机矿井简介 耿村矿属义马煤田西部的一个新矿井,设计能力为年产120万吨。煤层总厚度为19.41米,煤层顶板属易冒落的Ⅰ级顶板。可燃体挥发分为39.3～41.59％,煤尘爆炸指数为49％。煤炭极易自燃,发火期为一个月左右。沼气相对涌出量为5～7米~3/吨,属低沼气矿井。 全矿有三个采煤队(两综一炮),三个开拓队,七个掘进队。刚组建的综掘队在东一区21—11071下巷施工。下巷设计长度820米,梯形金属支护,净断面为9.29米~2。东一区沼气涌出量普遍偏高,特别是11071下巷,因有断层,又靠近煤层合并线,沼气涌出量接近高沼水平。AM—50型综掘机和配套使用的SCF—6型除尘机就布置在21—11071下巷。
Gengcun Mine began using SCF-6 dust removal fan in August last year and encountered many problems. Some detours were taken and some achievements were also made. First, trial dust mine Introduction Gengcun mine is a new mine in the west of Yima Coalfield, designed to produce an annual output of 1.2 million tons. The total thickness of the coal seam is 19.41 meters. The roof of the coal seam is a Grade I roof that is easy to fall. Combustible body volatile was 39.3 ~ 41.59%, coal dust explosion index was 49%. Spontaneous combustion of coal, the firing period of about a month. Relative emission of biogas is 5 ~ 7 m ~ 3 / t, which is a low-methane gas mine. There are three mining coal mines (two integrated artillery), three pioneering teams, seven driving teams. The newly formed digging team in the East District 21-11071 under the lane construction. The length of the next lane design 820 meters, trapezoidal metal support, the net section of 9.29 m ~ 2. The emission of biogas in Dongyi District was generally high. Especially in 11071 Xiaoxiang Lane, due to the fault and the coal seam merger line, the emission of biogas was close to that of the high marsh. AM-50-type excavators and supporting the use of SCF-6-type dust removal machine is placed in 21-11071 under the lane.
