一、探矿坑道在地质勘探工作中的作用坑道施工在地质勘探工作中起着重要的作用，它对矿山的规模、矿山的服务年限、开采条件、开采时涌水量的确定等起着主导作用。有些金属矿山为了获取高级储量，必须采用坑道揭露矿体，需要布置大量的沿脉和穿脉坑道。采用大量的坑道揭露矿体，其优点很多，能直接观察矿体的形状和矿体深部的变化情况，对地质取样也方便准确，有些探矿坑道还可供采矿利用，起到探矿和采矿相结合，加速矿山建设，节约国家资金的显著作用。可是探矿坑道也有不足之处，每米成本为钻探的4—5倍，掘进时间长。总的来讲，坑探对某些矿种由于取得的地质资料准确可靠，可以彻底弄清楚地质构造、涌水量的大小、埋藏情
I. The Role of Prospecting Tunnels in Geological Exploration The construction of tunnels plays an important role in the geological exploration work. It plays a leading role in the scale of the mine, the service life of the mine, the mining conditions, and the determination of water inflow during mining. Some metal mines in order to obtain advanced reserves, must be used to expose the ore body tunnel, the need to arrange a lot of along the vein and perforation of the tunnel. The use of a large number of tunnels expose the ore body, which has many advantages, can directly observe the shape of the ore body and changes in the depth of the ore body, the geological sampling is also convenient and accurate, and some of the prospecting tunnel is also available for mining, play a combination of prospecting and mining , Accelerate the construction of mines, and save the significant role of state funds. However, there are also inadequacies in prospecting tunnels. The cost per meter is 4-5 times that of drilling and the driving time is long. In general, pit exploration on certain minerals because of the geological data obtained is accurate and reliable, you can thoroughly clarify the geological structure, the amount of water, buried feelings
