随着采煤技术的推行以及巷道布置的改革深化,大雁矿区煤巷进尺比重迅速增长,进而推动了以煤巷锚杆支护为中心的煤巷支护改革的全面展开。在2001年大雁矿区第二煤矿煤巷总进尺为3707m,其中综掘进尺为2861m,占总进尺的77.18％。在2002年第二煤矿煤巷总进尺为3147m,其中综掘进尺为2485m,占总进尺的78.96％,煤巷进尺全部锚杆支护。这种支护方式成为大雁矿区第一、二煤矿煤巷主要支护方式,并将以良好的支护效果和显著的经济效益,日益显示出强大的生命力。
With the implementation of coal mining technology and the deepening of roadway layout reform, the proportion of coal tunnels in Dayan Mining Area has rapidly increased. This in turn has promoted the full implementation of the reform of coal roadway support centered on the bolting of coal roadways. In 2001, the second coal mine in Dayan Mining Area had a total footage of 3707m, of which, the total footage of fully mechanized excavation was 2861m, accounting for 77.18% of the total footage. In 2002 the second coal mine roadway total footage of 3147m, of which fully mechanized excavation footage is 2485m, 78.96% of the total footage, coal roadway footage all bolt support. This way of support has become the first and second coal mine Dayuan mine main supporting way, and will be a good supporting effect and significant economic benefits, increasingly showing strong vitality.
