光面爆破是煤矿巷道掘进的一项新技术,它既保持了围岩的自身强度,又增加了巷道的美观度,但是如何提高光面爆破掘进速度,却一直阻碍着这项技术的推广。以杜庄煤矿为例,就这一问题进行了独到的阐述。先介绍了杜庄煤矿的基本情况,然后从光面爆破具体的优点及现状、光面爆破与机械结合技术方面和光面爆破的效果评价做了具体的描述,为下一步这项技术的推广奠定了基础,为以后同类型煤矿的相关技术提供了良好的借鉴。 Smooth blasting is a new technology for roadway driving in coal mines. It not only maintains the strength of surrounding rock itself but also increases the aesthetics of the roadway. However, how to improve the speed of smooth blasting has always hindered the promotion of this technology. Taking Duzhuang Coal Mine as an example, we have made a unique explanation on this issue. First introduced the basic situation of the Duzhuang coal mine, and then from the concrete advantages and status of smooth blasting, smooth blasting and mechanical combination technology and smooth blasting effect evaluation made a specific description for the next step of the promotion of this technology laid The basis for the future of the same type of coal related technologies provide a good reference.
