矿产资源勘查是指依靠地质科学理论,运用各种找矿方法发现并探明矿产的地质工作。
1、减量化
矿产资源勘查是发现矿床并查明其中的矿体分布、矿产种类、质量、数量、开采利用条件、技术经济评价及应用前景等,满足国家建设或矿山企业需要的全部地质勘查工作。矿产资源埋藏于地下,具有稀少、隐蔽、复杂等特点,其勘查过程常常需要采用地质填图、物探、化探、遥感地质等方法,应用钻探、坑探等技术手段,需要进行测量、编录、取样、化验、实验、储量计算、技术经济评价和可行性研究等工作,需要大量的人力、物力和资金投入。且一个矿产资源地从发现、查明到开发需要经过很长的周期。因而,矿产资源勘查是一项极具风险的工作。由此可见,在矿产资源勘查阶段就开始贯彻循环经济的原则十分重要。
2、原则
为遵循减量化原则,首先,应减少不必要的投入,根据矿种稀缺程度的不同,优先安排社会经济发展中长期急需的稀缺程度高的矿种进行勘查。其次,根据河南省矿产资源共伴生矿产较多的赋存特点,在勘查过程中应遵循循环经济的减量化原则,同一探矿权范围内应力求多目标立体勘查。如金矿权分布范围内,除赋存金矿外,还可能有其他矿种,存在铅锌矿、银矿、钼矿等共生情况。根据目前的探矿权设置政策,探矿权人在勘查过程中主要是针对勘查矿种的勘查,这种勘查行为不符合循环经济的减量化原则。应制定相关政策允许其他矿种的勘查,达到事半功倍的效果。
Mineral resource exploration is to rely on the theory of geological science, the use of a variety of prospecting methods to find and explore the geological work of mineral.
1, reduction
Mineral resource exploration is to find ore deposit and to find out the distribution of ore body, mineral species, quality, quantity, exploitation conditions, technical economic evaluation and application prospect, etc., to meet the needs of national construction or mining enterprises all the geological exploration work. Mineral resources buried underground, with scarce, subtle and complex characteristics, the prospecting process often require the use of geological mapping, geophysical and chemical exploration, remote sensing geology, by drilling, pitting technical means and need to work measurement, logging, sampling, laboratory test, experiment, and reserves calculation, technical and economic evaluation and feasibility study, need a lot of manpower, material resources and capital investment. And the discovery of a mineral resource, to find out the development needs to go through a long period of cycle. Therefore, mineral resource exploration is a very risky work. Thus, in the mineral resources exploration stage is very important to implement the principle of circular economy. [1]
2, principle
In order to comply with the principles of reduction, first of all, we should reduce the unnecessary inputs, depending on the degree of scarcity of mineral resources, giving priority to social and economic development in long-term need of high degree of scarcity of minerals prospecting. Secondly, according to the characteristics of mineral resources in Henan Province, we should follow the principle of reduction of circular economy in the process of exploration, and the same exploration right should be more than the target. Such as gold weight distribution range, in addition to the gold deposit, may also have other minerals, lead and zinc, silver, molybdenum and so on symbiotic situation. Set up the policy according to the current prospecting, prospecting people in the exploration process is mainly according to the prospecting of mineral resources exploration, the exploration behavior does not comply with the principles of circular economy reduction. We should formulate relevant policies to allow exploration of other mines, to achieve a multiplier effect.
