摘要
倾斜、缓倾斜中厚矿体的开采普遍存在着矿石运搬、矿柱回采和顶板管理等三大技术难题,倾斜壁式粗颗粒水砂充填采矿方法则较好地解决了这些难题。文章从采矿方法设计构思出发,系统地描述了这一新型采矿方法的特征和构成要素以及回采实践经验与各项技术经济指标,并就存在的问题和需进一步完善的工作提出了看法和建议。
Ore hauling, ore pillar recovering and roof management are three major technological problems encountered in mine of inclined and gentle ore bodies of medium thickness. Such problems can satisfactorily be solved by inclined-back (wall) hydraulic filling method of coarse sizeflushing. This paper systematically describes this new method, including mine planning, ore block parameters, stopping experience and all economic and technical performances obtained. It also offers suggestions and proposals for solving the problems existing with this method to improve the technology.
