摘要
北沟采区范围内1号矿脉为主矿体，保有储量260万t，平均品位0．34％，钼矿平均厚度为3～6m，围岩陷落角上、下盘均为65°。为充分回收利用国家宝贵的矿石资源，积极增加企业的经济效益，本文针对北沟采区1号矿脉资源特点，研究制定了资源开采工程技术方案，并详细进行了技术论证和经济分析，以确保该部分矿产资源能安全高效地获得回收。
The 1^# vein is the main ore body in Beigou stoping, hold reserves of 260 × 10^4 t, average grade of 0.34%, molybdenum mine average thickness of 3 -6 m, wallrock angle of draw of roof and foot wall of 65°. According to resource peculiarities, the technology project of mining Beigou stoping area 1^# vein is researched and established, techno -demonstrate and economy analysis are done in order to reclaim and utilize precious ore resource sufficiently, increase economy benefit actively.
