全面采矿法的特点是,在阶段中把矿段划分为矿块,矿块间不留间柱或只留少量间柱.一般在采空区留不规则矿柱或用人工支柱支护顶板.回采工作线沿走向或倾向全面推进.人员在采空区条件下作业.该法采切工程量少,工艺简单,方法灵活,矿损少,在我国金属矿山得到了广泛应用.过去一般用于矿岩稳至中稳,倾角小于25～30°,厚度在3～4米以下的矿床中.
The comprehensive mining law is characterized by the fact that the ore section is divided into nuggets during the stage, with no or only a few pillars between the nuggets, and irregular pillars or artificial pillars are usually used to support the roof in the goaf. Mining working line along the trend or tendency to promote the full operation of the staff in the goaf conditions.The method of mining less, simple process, flexible method, less mining loss, metal mines in China has been widely used in the past is generally used in Ore rock stable to moderate, dip less than 25 ~ 30 °, thickness of 3 to 4 meters below the deposit.
