  • 摘要

    由于我国西部矿区降雨稀少、蒸发强烈,形成了该区干旱缺水、生态环境脆弱的基本特征。以位于吐哈盆地的哈密煤田大南湖矿区为研究区,开展该生态脆弱区水资源保护性采煤(即"保水采煤")的水文地质基础研究,以及顶板水害防治与保水采煤相结合的可行性探索。在系统评价研究区主要煤层顶板含隔水层结构、隔水保护层的稳定性以及受保含水层开发潜力的基础上,以大南湖五号井1801首采工作面为例,开展了研究区顶板水害防治与保水采煤相结合的实践,提出了矿区高矿化度受保含水层水开发利用的初步方案,通过该工作面的成功试采初步取得了吐哈盆地生态脆弱区水资源保护性采煤的实践经验。提出并实践了吐哈盆地典型生态脆弱区顶板水害防治与保水采煤相结合工程,为指导作为新疆四大煤炭基地之一的哈密煤炭基地煤炭资源的绿色开采具有一定的理论及实际参考。

  • Abstract
    The ecological environment is relatively weak due to the low precipitation and high evaporation. The study area is the Dananhu mining area of Hami coal field,which is located in the Turpan-Hami basin. For the ecologically vulnerable area,the authors studied the hydro-geological conditions for water-preserved mining and its feasibility. The structure of aquiclude in the roof of major coal seam has been systematically assessed. Furthermore,the authors investi- gated the development characteristics of the height of the water flowing fractured zone,and studied the development po- tential of aquifer under protection. Then,the practical application for water-preserved mining had successfully conduc- ted at the 1801 working face of Dananhu No. 5 Coalmine as a case study. This study proposed a preliminary program for the development and utilization of protecting high salinity aquifer water, gaining experience for water-preserved mining in the ecologically vulnerable area of the Turpan-Hami Basin. This paper first put forward and practiced the roof water disaster control and water-preserved mining combining engineering in the typical ecological fragile area of Tuha Basin,providing theoretical and practical references for safely exploit the coal resources in Turpan-Hami coal field,which is one of the four major coal bases in Xinjiang Province.
