In the process of mining, much research was conducted on the control and reduction of the radiation hazards in underground uraniferous coal mine.

我国煤型铀矿资源的储量在我国铀矿资源总储量中占有一定比例。20世纪60年代后期我国开始了这类铀矿床的地下开采，在开采期间，对控制这类铀矿床地下开采中辐射危害的技术与管理措施开展了大量研究。20世纪80年代后期，因为多种原因，这类矿山被关闭。

At the first, the paper describes the importance and the present status of the application of wasteless mining in our country, and gives a special discussion for its conception ,research approaches, and some apply pathways for wasteless mining, then makes a brief description of decision-making and optimizing theories and methods applied in the paper's design and appraisal for the wasteless mining.

另外，为合理地控制采切时废料的混入，在采矿方法设计中还引入了衡量采准工作的采切废石混入率的标准与计算方法。采矿工艺过程的优化，主要是要设计选用最合适的采矿方案与最合适的采矿工艺。这是实现无废开采极为重要的一个方面，它直接影响着矿山的开采效益与无废开采效果。

Therefore, it has become an important development direction for our mining industry to protect mine's environment, and to keep mine production with continuance and steadiness for a long periodWithin recent years, many new problems were brought forward through wasteless mining experience, in which, the right design and objective appraise for the wasteless mining is one of its problems.

另外，作者在研究中提出的一些独到的见解与方法，对发展与完善无废开采设计与评价的理论体系有重要的意义。我们知道，实现无废开采的关键：一方面是要尽量扼制废料的产出，另一方面是要寻找有效的方法对产出的废料进行治理。而要扼制废料的产出，必须要根据矿山开采的特点，合理确定开采品位，减少废石的采掘，控制采矿过程中废石的混入。

At the aspect of resource appraise, the paper appraises and analyses it from its benefit and its mining grade, and puts forward up their methods for appraise and calculation, in order toTHE RESEARCH FOR THE THEORY OF WASTELESS MINING APPRAISEdecrease the brought waste in mining, and to increase the resource utilization and the benefit of the mining.

在无废开采程度评价方面，本文在前人的基础上，主要从无废开采效益、废料资源化程度，以及&四废&处理程度这三个方面进行评价，分别提出了系统而适用的评价方法和评价标准，完善和发展了矿山无废开采程度的评价体系。

Through reviewing all kinds of materials which can manufacture the milling ball s at present in our country, it finds that milling ball maked by low chromium cast is suit to the wear environments in waterish grindi.

通过对目前使用的磨球材质进行综合考察，以磨球的性价比为标准，认为低铬铸铁磨球是一种适合于金属矿山湿式球磨机磨损工况的磨球。
