摘　　要：斜孔钻探是运用在金属固体勘探中,对于急倾斜矿体或地层自然倾斜严重的地层,技术上难以控制的矿区,为保证施工质量,设计时常常要求斜孔施工。斜孔钻探工艺不仅扩大了矿产储量、加快了勘探速度并节约了大量的钻探施工费用。解决了直孔无法达到的地质要求目的,而且还能深入到过去直孔无法深入的矿床禁区,能获得显著经济效益。The slant-hole drilling is the use of solid metal exploration, ore body or the ground for the steep slope serious nature of strata, technically difficult to control the area, to ensure the construction quality, design often requires slant-hole construction, slant-hole drilling technique not only expanded the mineral reserves and accelerate the speed and save a lot of exploration drilling construction costs. Hole can not be solved until the geological requirements to achieve the purpose, but also deep into the hole can not be the last direct deposit depth restricted access to significant economic benefits.
