本文针对中厚缓倾斜矿床的特点,指出利用传统的露天采矿工艺和设备,不能满意地解决缓倾斜矿开采中“三角体”的钻孔及采装问题。解决“三角体”的一次成孔和岩、矿分别爆破、采装是改进中厚缓倾斜矿床露天开采工艺的关键。 In this paper, according to the characteristics of moderately-to-moderately-sloping deposits, it is pointed out that the use of traditional open-pit mining technology and equipment can not satisfactorily solve the problem of “triangle” drilling and mining in gently inclined mining. Solving the “Triangle” a hole and rock, mine blasting, respectively, mining and dressing is to improve the surface of the gently inclined mining open pit mining process is the key.
