以潞安集团的王庄煤矿后备区所处绛河水体下的一中厚煤层实践情况作为本文研究案例。文章主要结合王庄煤矿后备区绛河实例,对其河床复合水体下压煤现实情况与开采水文地质条件进行了分析。即主要通过对绛河开采水文地质条件及中硬与坚硬的覆岩综采破坏规律进行了分析探讨,得出了绛河下中厚煤层结合厚度的差异运用针对性的不同技术工艺,并配套运用科学合理的防水措施,可以实现水体下厚煤层快速综放开采的结论。
Taking the practice of a medium-thick seam under the Jiang River water body of Wangzhuang Coal Mine Reserve Area of Lu’an Group as the case study in this paper. The article mainly combined with the example of the Jiang River in the backup area of Wangzhuang coal mine, analyzed the actual situation and the hydrogeological conditions of coal mining under the composite water bodies in the river bed. That is mainly through the hydrogeological conditions of the Jianghe mining and medium and hard overburden comprehensive mining failure of the law were analyzed and studied, the thickness of the Middle and Thick Seam Jiangjiang under the thickness of the difference in the use of targeted technology and technology, and supporting the use of Scientific and reasonable waterproofing measures can realize the quick and fully mechanized top coal caving under the water body.
