岩金矿山无底柱分段崩落采矿法拉槽技术研究

摘要

Based on the mining practice of sublevel caving method in the Yingezhuang gold mine, this paper studies the inclined slot hole grooving method in block caving application, and provides theory basis and feasible measure for the inclined parameters of inclined slot hole. Practices prove that the inclined slot hole grooving method holds advantages such as safe operation, less excavation work and high efficiency and so on. The method is worth promoting.%基于尹格庄金矿无底柱分段崩落采矿法开采实践,研究了倾斜深孔拉槽法在岩金矿山分段崩落采矿法开采中的应用,并进行了理论推导,为倾斜中深孔的长度、倾角等参数的确定提供了依据.应用实践表明,倾斜深孔拉槽具有作业安全、掘进工程量小、作业效率高等优点,值得推广应用.
