市场经济体制执行地质勘探规范的有关问题讨论

市场经济体制下地质勘探工作的资金投入一般要由开采单位负担,而这部分资金属于前期投入,需要贷款来解决,现行的地质勘探规范已难适应地质工作的需要。在有一定工作基础的中小型矿山地质勘探工作中,对矿体的控制、水文地质、矿石可选性试验等工作程度,高级储量比例,勘查周期等方面,宜根据实际情况,合理的加以确定。

CEMENT/SOLUBLE SILICATE PROPORTIONAL MUD: APPLICATION TO LESS STABLE GROUNDS

Cement/soluble silicate proportional mud, a chemical preparation to scale, is capable of cementing loose parts of less stable grounds together and filling their cracks after being poured into them, thereby forming a "stonelike body" . This will greatly improve the physical and chemical strengths of the grounds because of the body which is structured as stronger and chemically more stable. This chemical mud incorporates the advantages of both cement mud and soluble silicate mud.
