The concept and technological system of green mining is put fo reword and the developing trends of green mining are pointed out.

本文提出了绿色开采的概念和绿色开采的技术体系，指出了绿色开采的发展趋势。

As a new rodless oil production equipment, the ESPCP can be applied in high-viscosity, wax content, sand or gas content well, and radically resolve problems met by sucker rod screw pump applied in heavy oil production such as break of rod , offset-abrasion of rod tube and limit to apply in deep or deviation well .The unit also overcomes the low efficiency of ESP pumping high viscosity oil and especially applied in directional well .

潜油电动螺杆泵作为一种新型的无杆采油设备，可用于高粘度、含腊、含砂、含气原油的开采，从根本上解决了有杆螺杆泵在稠油开采中的抽油杆断脱、杆管偏磨和在深井、斜井中使用受到限制的问题，而且也克服了潜油电动离心泵输送稠油效率低的缺陷，特别适用于定向井的原油开采。

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。

In the paper, a integrate evaluation system for wasteless mining is set up from theory to practice. The plan and design is very important to the realization of wasteless mining.

从矿产资源特点、设计的科学思维基础、无废开采的特点到无废开采设计原则、内容及程序等方面进行了完整系统的讨论，形成了一套完整的无废开采设计方法、体系。

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。

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。

If there is enough gold in the deposit to be produced economically, a mine is permitted and loped.

如果矿床里有足够的黄金在经济上有开采价值，便办理该矿山开采的报批手续，着手进行矿山开采的准备工作。

Exchange the heating well and the oil extraction well that the much more above-mentioned well electricity heat the oil shale retorting mine, continue to heat to mine. 5 after years, the temperature that is apart from to heat the or so place of 6 meters of well is also only is 500°C, but heat whole temperatures of the nearby rock strata of wells all very high, cause the calories follow the peripheral rock strata in great quantities lost.

2将上述多井电加热油页岩干馏开采的加热井与采油井交换位置，继续加热开采。5年后，距加热井6米左右的地方温度也仅为500℃，而待采油页岩层与邻近地层的接触面处整体温度很高，说明在整个开采过程中油页岩层向邻近地层散失了大量的热。

The success rate of mining is up to 99% and with little waste of stone ballast and dust and pollution reduction.

日开采量50～100立方，成本85元/立方，开采石材的成品率99％以上，极大的提高自然利用率，开采产生的石渣、灰尘少，大大降低污染程度。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
