  • Publication number: 20200378258
    Abstract: A method for classifying a phreatic leakage disaster level in shallow coal seam mining includes the following steps: S1. arranging a monitoring hole in a coal mine working face and burying a telemetering water level gauge to perform water level monitoring; S2. monitoring a ground elevation, calculating a ground subsidence amount, and collecting drilling footage information; S3. plotting variation relationship curves of drilling footage and phreatic water level as well as drilling footage and ground subsidence according to monitored information, respectively; and S4. comparing the curves with a no-leakage graph, a slight-leakage graph, and a heavy-leakage graph, and determining a leakage level; and S5. further classifying a studied area as an environmental disaster area or an environmentally friendly area.

  • Publication number: 20200370433
    Abstract: The present invention relates to the field of prevention of a water disaster in coal mining, and discloses a risk evaluation method of an overburden bed-separation water disaster in a mining area. In the prior art, prevention of the bed-separation water disaster is achieved mainly by making bed-separation water “cut-off holes” and “diversion holes” underground; however, the degree of a roof bed-separation water disaster in the mining area has not yet been qualitatively or quantitatively evaluated and analyzed, resulting in blindness of the prevention of the bed-separation water disaster. In order to solve this problem, the present invention provides a risk evaluation method of an overburden bed-separation water disaster in a mining area, which includes the following steps: S1. collecting geological information about strata in the mining area; S2. calculating the height of a water-conducting fissure zone in the mining area; S3.

  • Publication number: 20200234170
    Abstract: A method for classifying eco-geological environment types based on coal resource exploitation solves the problem in the prior art of a lack of combined consideration of different geological and ecological environments on the surface in a to-be-mined area before coal mining. Based on surveys of ecological, hydrological, and geological information of the area, and by means of a Fuzzy Delphi Analytic Hierarchy Process (FDAHP) and weighted fuzzy C-means clustering, the present invention determines different eco-geological environment types. According to the existing ecological, hydrological, and geological information, the present invention can rapidly and effectively classify the different eco-geological environment types, and further determine eco-geological features and their sensitivity to coal resource exploitation.
