Research on the Mining on the Coal Face without Sand Control Seam under the Poor Water-Content Loose Aquiclude

双层含水层系统的数值计算方法弱松散含水层下无防砂保护层开采研究

In the past, focal point of the work is on rock thickness and lithology and combination and so on of macroscopic aquiclude characteristics.

以往，人们偏重于对隔水层岩性、厚度及组合情况等宏观特征研究。

According to properties of aquiclude, the experiments determine the similar material and ratio law of aquiclude and realize stress-strain complete resemble simulation of clay aquiclude.

根据隔水层性质，实验确定了隔水层相似材料及其配比规律，实现了粘土类隔水层的应力应变全程相似模拟。

The results show that aquiclude of coal seam floor has obvious elimination to water head, and the actual water pressure exerting to the effective water resistant layer is lower than that of aquifer.

结果表明：隔水层的原始导高带对含水层水头具有较大的消减作用，作用于有效隔水层的实际水头压力远小于含水层的水头压力。

The experiments obtain that the key strata of bedrock in shallow seam has a significant effect on the stability of aquiclude and clay as well as loess aquicludes are key stratum of water-preserved-mining.

实验得出，近浅埋煤层顶板基岩关键层的运动对隔水层稳定性具有明显作用，粘土和黄土隔水层是保水开采的隔水关键层。

Because an aquiclude penetration of oil from oil wells, the shallow aquifer of an oil field was contaminated, which directly affect the local residents' drinking water safety, so selecting appropriate remediation method to treat the polluted groundwater is urgent.

某油田开采厂区由于油井返水事故造成了浅层地下水污染，直接影响到当地居民的地下水饮水安全，急需选取适当的修复方法对该地区地下水进行治理。

The simulation of stability of the mining induced aquiclude is very important for water conservation mining of the shallowly buried coal seam and the development of similar materials of clay aquiclude is the base for the simulation experiment.

采动隔水层的稳定性模拟是研究浅埋煤层保水开采的关键，隔水层相似模拟材料的开发则是模拟实验的基础。

An aquiclude stores water but does not transmit significant amounts.

一个不透水层只存水但不能大量导水。
