摘要
本文从矿山技术经济效果出发,提出了(极)薄脉状矿床开采中脉群合采区圈定的准则和相应的计算公式,并以实例说明了合采区圈定的方法.
In view of technological and economic efficiency, this paper presents the principles of delimiting the mining area of (extremely) thin veins which can be minable and payable by using multi-vein mining method,The working procedure, together with the formulas used for calculation is given and illustrated by actual examples.
