Research Status of Environmental Pollution and Comprehensive Utilization of Mine Waste Rocks
-
摘要:
在矿产资源开采过程中会产生大量不含矿的围岩和夹石，称为废石。废石是一种固体废弃物，一般以堆存的方式存放。随着我国对矿山环保要求的不断提高，废石的大量堆存及其造成的环境污染已成为现在亟需解决的问题。本文介绍了矿山废石堆存对周边水体、土壤和大气造成的危害，并指明目前这类废石的综合利用方式主要包括有价金属提取、工程化利用以及建材制造等，以期为后续矿山废石的无害化及资源化综合利用提供借鉴。
Abstract:A large number of surrounding rocks and sandwiched rocks without minerals are produced in the process of ore mining, which are called waste rocks. Waste rocks are solid wastes which are usually stored in storage. With the continuous improvement of mine environmental protection requirements in China, the waste rock storage and its environmental pollution have become an urgent problem. This paper comprehensively introduces the comprehensive utilization status of waste rocks and the harm caused by mine waste rocks to surrounding water, soil and atmosphere. The comprehensive utilization methods of the kind of waste rocks are points out, which mainly includes valuable metal extraction, engineering utilization and building materials manufacturing. It can provide references for the subsequent harmless and resource comprehensive utilization of mine waste rocks.
