September 2，Good news from the 6th Science and Technology Innovation M88 appConference of Shaanxi Coal Group，The "Key Technologies and Demonstration of Water Resources Protection and Utilization and Ecological Reconstruction in Northern Shaanxi Coal Mining Area" that Shaanxi Mining Company mainly participated in and completed won the first prize of Science and Technology Award，The project "Research on the Evolution of the Sedimentary Environment of Ancient River Channels and the Dynamic Changes of Groundwater in the Southern District of Shenfu" won the third prize。The "Key Technologies and Demonstration of Water Resources Protection and Utilization and Ecological Reconstruction in Northern Shaanxi Coal Mining Area" project won the 2022 China Coal Industry Association Special Award。

Over the years，The company focuses on cutting-edge technology in the industry，Continuously improve the scientific and technological innovation management system，Building a scientific and standardized project management model，With universities、Close cooperation with scientific research institutions，Building an innovation platform integrating industry, academia and research。

The "Key Technologies and Demonstration of Water Resources Protection and Utilization and Ecological Reconstruction in Northern Shaanxi Coal Mining Areas" project is a project of Shaanxi Coal Group to explore a new model of ecological management of coal mining，Developed in cooperation with the team of Academician Peng Suping of China University of Mining and Technology (Beijing)。Insist on “developing gold and silver mountains”，Rebuilding Green Mountains" governance concept，Systematic observation of overlying rock movement through coal mining in aeolian sand and loess gully areas，Mastered the development rules of surface cracks in two types of landform m88 casinounits，Constructed a coal seam mining ground collapse damage prediction model；Developed scientific mining technology to slow down ground collapse、New crack filling technology and micro-landform transformation technology，Realized uniform settlement of the surface of the mining area；The mechanical action mechanism and safety threshold of seepage on the surrounding rock in the goaf were analyzed and determined,Provides technical support for the utilization of water resources in goaf areas；Constrained by water resources carrying capacity，Optimize the ecological function zoning of subsidence areas，Using the three-dimensional reconstruction method of economic forest-ecological forest，Building a comprehensive reclamation and recycling system of plants, soils and microorganisms in mining areas，Acquired good ecological landscape configuration and land use model。

After 3 years of scientific and technological research，A governance model for coordinated development of ecological restoration and industrial economy constrained by water resources carrying capacity has been formed in the arid area of ​​northern Shaanxi，Established 4 demonstration areas with different modes,That is, 1 ecological factor self-repair dynamic monitoring area、1 gangue filling ecological reconstruction demonstration area、1 modern agricultural soil improvement demonstration area、1 biological aerial seeding comprehensive ecological restoration demonstration area；Realize four comprehensive three-dimensional ecological restoration and landform landscape demonstration areas under different reclamation models in the northern Shaanxi mining area；Promotion demonstration area 5.more M88 appthan 40,000 acres，Profit 12.95.1 billion yuan，Place 2520 people。

The "Research on the Evolution of Ancient River Channel Sedimentary Environment and Dynamic Changes of Groundwater in Shenfu South District" project was carried out by the team of Professor Fan Limin of Northern Shaanxi Mining Company and Shaanxi Provincial Geological Environment Monitoring Station (Shaanxi Provincial Geological Hazards Center)。The project takes the ancient river channels developed in the coal-bearing rock series and overlying strata in the southern Shenfu District as the research object，Already have outcrops in the area、Drilling、Based on seismic data analysis,Through field survey、Drilling、Analysis test、Technical means such as numerical simulation and series compilation，Revealing the sedimentary filling evolution rules of coal-bearing rock series,For key ancient river channel aquifers and mineable coal seams、Containing (isolating) water layer spatial configuration relationship for regional morphological characterization and positioning prediction；Dividing the groundwater system of ancient river distribution areas，Analysis of groundwater circulation evolution model in ancient river channel distribution area，And evaluate the amount of groundwater resources under current conditions；Find out the spatial relationship between ancient river aquifers and shallow mineable coal seams，Proposed the technology of zoning grouting to reduce water and retain water in ancient river channels,Project results provide technical support for safe production and water resources protection in mining areas，Provide support for mine safety production and sustainable m88 casino reviewdevelopment，Greatly promotes ecological protection and high-quality development in mining areas。(Hui Shuanglin)
