Key technologies and engineering practices for green drainage of the Jurassic burnt rock-hosted water in the Shenfu mining area
摘要
Abstract
[Objective]In the northern part of Shaanxi Province,coal mining has led to a pronounced contradiction between coal mining and water conservation,along with a serious threat to China's ecological redline.These challenges necessitate transforming the mine water drainage pattern in coal mines.Green mine water drainage represents a key ap-proach to achieving coordinated coal-water production in areas containing burnt rocks.[Methods]Focusing on the con-servation-oriented utilization of the Jurassic burnt rock-hosted water in a coal mine within the Shenfu mining area,this study explored a solution to coordinated coal-water production in areas affected by burnt rock-hosted water from the per-spectives of the scientific connotation of green drainage,the identification of the hydrogeological characteristics of burnt rocks,and ultra-long-distance catchment-drainage integration.[Results and Conclusions]From the perspective of its scientific connotation,green mine water drainage,adopting the full-lifecycle,systematic control as its core principle,aims to achieve coal-water coexistence through mine water reduction from sources,harmless treatment during the pro-cess,and end-of-pipe reutilization.In the Shenfu mining area,the Jurassic burnt rocks are fracture-vug dual media,with water yield properties showing a weak-strong-weak-weak pattern vertically.The burnt rocks associated with the No.2-2 coal seam constitute the dominant high-quality aquifer in the area,exhibiting three water storage modes:lateral expos-ure in gullies,recharge beneath gentle slopes,and deep confined storage.Accordingly,prevention and control measures tailored to different coal seams,water quality conditions,and water types are proposed.A comparison of three drainage technologies indicates that the conventional underground borehole drainage and surface vertical-well pumping have dis-tinct advantages and limitations.In contrast,the surface catchment-drainage integrated mode offers inherent advantages in terms of environmental friendliness and low energy consumption.Based on the undisturbed vertical borehole-forming technique using a full casing full rotary drilling rig and the shallowly buried near-horizontal directional drilling tech-nique,key technologies for catchment-drainage integration were developed.Furthermore,a green drainage system for burnt rock-hosted water was successfully deployed over an ultra-long distance of 3500 m,achieving efficient and envir-onmentally friendly drainage.Focusing on key technologies for green mine water drainage,the results of this study en-rich the scientific connotation of green and water-preserved coal mining while also providing novel insights into the pre-vention,control,and utilization of mine water under similar geological conditions.关键词
