物探找隐伏矿的几个技术问题

本文就物探”直接“找矿和”间接“找矿建立了相应的概念;论述了建立地质-地球物理模型的必要性,指出模型与模式是不同的概念,并提出了建立模型的步骤及流程;根据矿床的物性特点及埋深的不同,提出四种物探找矿方案、具体任务和可采用的方法,为找深部矿提出用物探立体填图加井中物探的方案.

SOME TECHNICAL PROBLEMS CONCERNINGGEOPHYSICAL PROSPECTING FOR CONCEALEDORE DEPOSITS

This paper has established corresponding concepts for geophysical "direct"and "indirect"ore prospecting, dealt with the necessity of establishing geologi-cal-geophysical model, pointed out that model and pattern are two differentconcepts, and brought forward the precedure and process for establishing themodel. According to physical properties and different buried depths of ore de-posits, the paper advances four schemes for geophysical prospecting, theirspecific tasks as we1l as usable methods. As for seeking deep-seated ore depo-sits, a scheme of geophysical three-dimensiona1 mapping plus boreho1e geophy-sical prospecting is put forward.
