摘要
改革开放以来,全国地勘行业发生了深刻变化,取得了一定成绩,但也存在一些问题。有的固体矿产普查项目面积过大,工程间距过稀,致使普查任务难以完成。控制固体矿产普查区面积不宜过大,以满足“三线(勘探线)两点(探矿工程)”的布设为宜。普查区内工程的布置要达到总体控制,亦即该矿种该勘探类型C级储量控制网度放稀一倍。
Deepgoing changes have taken place in the country' geological prospecting sector since reform and opening up, with both certain shortcomings and achievements, particularly in a view of reconnaissance survey of solid minerals. The survey task used often not to be fulfilled because of overspreading survey area and oversparse project spacing. Generally, survey area will desirable while confined to a scope of “three lines, two spots”, namely, meeting need of the future prospecting works for at most three prospecting lines and two prospecting projects. According to this overall arrangement, investigation scope of any ore deposit will suitable if based on doubling the exploring interval necessary for achieving the deposit's C class resrves.
