一、坑探在探矿工作中的作用坑探是加速取得地质成果，提高地质工作质量的重要手段。地质人员除了用它揭露地表，验证物化探，配合钻探弄清矿体产状，求得储量外，在稀有金属、分散元素及不规则的矿体勘探方面，仍是一种主要手段。它的特点是能够直接观察现象和矿体产状，取样方便准确，有些探矿坑道，可提供采矿利用，起
First, the role of pit exploration in prospecting Pit exploration is an important means to speed up the geological achievements and improve the quality of geological work. In addition to using it to reveal the surface geological, geophysical and geochemical exploration, with drilling to clarify the shape of ore bodies, to obtain reserves, in the rare metals, scattered elements and irregular ore exploration is still a major means. It is characterized by the ability to directly observe the phenomenon and the shape of the ore body. The sampling is convenient and accurate. Some prospecting tunnels can provide mining utilization.
