一、勘探而未建设的矿床积压了资金矿产只有开发利用,才能变成社会的物质财富,构成经济效益。因此,所勘探矿床利用了多少,是衡量矿产地质工作经济效益的重要标志。粗略统计,解放以来本省共勘探各类矿床(石油未计)284个,已建设开采的155个,利用率达54.6％。由本局系统勘探的128个,利用率32.8％。各类矿种中利用率最高的是煤,最低是铁。煤87.3％(按井田计89.1％)。建材71％,化工原料38.5％,冶金辅助原料
First, exploration and construction of non-built deposits backlog of capital and mineral development and utilization only in order to become the material wealth of society, constitute economic benefits. Therefore, how much exploration deposit is utilized is an important symbol to measure the economic benefit of mineral geology work. Rough statistics, the liberation since the exploration of various types of deposits (not counting oil) 284, has been the construction of 155, the utilization rate of 54.6%. 128 of the systems explored by our bureau have a utilization rate of 32.8%. The highest utilization rate of all types of minerals is coal, the lowest is iron. 87.3% of coal (89.1% by field). 71% of building materials, 38.5% of chemical raw materials, metallurgical auxiliary materials
