煤矿开采

One type of serious accidents occurred in mine exploitation is water irruption.

矿井突水灾害是煤矿开采中特大事故类型之一，因此采矿前期的一个重要的地质任务就是探测采区内构造的分布及地层的含水性，查明是否存在断层、溶洞、裂隙等对开采可能带来不良影响的地质构造。

Especially, the subsidence caused by coal mining has been forecast by the way of probability integral. Moreover, with the application of Object Linking and Embedding, the system can draw subsidence contours and predictal results can be visualized quickly.

And then through analyzed the component of the pollutant in the region's groundwater, and considered the good and bad points of each assessment method, we adopted the fuzzy comprehensive evaluation method, and estimated the vitiation of the ground water, which result is conform with the actual degree, and has realized the of the fuzzy appraisal.

本文针对煤矿开采对地下水污染的问题，首先根据研究区域自然地理与水文地质条件分析了煤矿开采对地下水污染机理，然后通过对研究区域地下水污染物组分的分析，考虑各种评价方法的优缺点，采用模糊综合评判法，对煤炭开采对地下水的污染做出了比较合乎实际的评价，并实现了模糊评价的电算化，同时利用Matlab分析了煤矿开采对地下水污染的趋势。

Backfilling mining is an effective technical approach to solve the environmental problems and control surface subsidence caused by coal mining.

充填开采是解决煤矿开采造成的环境问题，控制地表沉陷的有效技术途径之一。

As one of major monitoring techniques for forecasting the disasters in mine, Microseismic signal contains some special characteristics, such as rich composition of the spectrum and wide frequency band.

在煤矿开采过程中，煤层底板突水、淹井事故时有发生，严重影响煤矿的正常生产，但目前其预测的可靠程度与生产实际还有较大的差距。
