一、推行情况我鑛自推广硬质合金钎头凿岩和采取提高风压以及改善劳劫组织等有效措施之后,凿岩工效有了显著的增长,台班效率在一年多的时间内提高了100％以上。以前每一台凿岩机在每一班内只能打一个工作面,现在如果再给一个工作面就不够用了。随着客观发展的需要,为了充分友挥凿岩潜在能力,迫切需要实行单机多面凿岩作业。我鑛鑛床为缓倾斜鑛体,倾斜度一般为12～15°和24～27°,鑛体厚度平均为5公尺。为了进行坑探工作,在沿脈卷道内每隔20～25公尺开凿穿脈。这样的布置方法,能在同一地区内准备出若干工作
First, the implementation of My mine since the promotion of hard alloy drill bit drilling and take to improve wind pressure and improve the robbery organizations and other effective measures, the drilling efficiency has been a significant increase in the efficiency of the station in more than a year More than 100%. Before each rock drill in each class can only play a face, and now if given a face is not enough. With the need of objective development, in order to give full play to the potential of rock drilling, single-plane multi-face rock drilling is urgently needed. The ore deposit is a gently sloping orebody with a slope of 12-15 ° and 24-27 °, with an average ore body thickness of 5 meters. In order to carry out pit exploration work, cut the pulse line every 20 to 25 meters along the winding path. This arrangement, in the same area to prepare a number of work
