一、基本情况建国以来,我国煤矿新建和扩建了几十个大中型矿区,增加了四亿多吨的生产能力,新井建设规模一直维持在一亿吨以上,每年投产矿井的能力为一千万吨左右,原煤生产能力猛增到六亿多吨。所取得这些成绩是与我国井巷掘进技术的发展分不开的,在立井、斜井、岩巷、煤巷掘进机械化方面,以及锚喷支护、爆破器材、动力单一化和转载运输设备及工艺方面都取得了大批可喜的、应用于生产的科研成果。统配煤矿掘进装载机械化程度由解放初期的2％提高到36.5％,基建矿井的掘进装载机械化程度由解放初期的5％提高到80％以上,为加快井巷掘进速度、减轻笨重体力劳动和改善井下安全生产
First, the basic situation Since the founding of the PRC, China’s coal mines and the expansion of dozens of large and medium-sized mining area, an increase of more than 400 million tons of production capacity, the new well construction has been maintained at 100 million tons or more, annual production capacity of 10 million mines Ton, raw coal production capacity soared to 600 million tons. These achievements are inseparable from the development of the well excavation technology in our country. In the mechanized aspects of vertical shaft, inclined shaft, rock roadway and coal tunneling, as well as the equipment of anchor and shotcrete support, blasting equipment, power unitization and reloading transportation equipment and Technology has made a large number of gratifying, used in the production of scientific research. The degree of mechanical mechanization of coal mining and embarkation with coal mines increased from 2% to 36.5% in the early period of liberation, and mechanization of tunneling and loading of infrastructure mines increased from 5% to 80% in early liberation. In order to speed up tunneling and reduce heavy physical labor and improve Underground safety production
