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.

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.

Abstract: Disclosed are a microgranular water-soluble fertilizer co-produced from potassium nitrate by tower melt and a method of preparing the same, which relate to the technical field of production of water-soluble fertilizers. The microgranular water-soluble fertilizer co-produced from potassium nitrate by tower melt is prepared from potassium nitrate concentrate, urea, industrial monoammonium phosphate, water-soluble ammonium polyphosphate, potassium sulfate, EDTA-Fe, EDTA-Zn, EDTA-Mn, boric acid and ammonium heptamolybdate. The microgranular water-soluble fertilizer product co-produced from potassium nitrate by tower melt has balanced and stable nutrients. The product is microgranular, has a smooth appearance, is less susceptible to agglomeration, is easy to be absorbed and utilized by crops, and contains a full range of nutrients. In addition, the product is produced by a process employing fully automatic dispensing equipment, which mainly integrates “dispensing, mixing and packaging” and is fully automated.

The method optimizes back-feeding of out-of-service areas by minimizing power loss, switching, unserved loads and voltage/current violations. The efficiency of the algorithm is further increased through the use of a reactive Tabu search to prevent duplicate candidate systems.

Abstract: Biogenic silica is produced by combusting a biogenic source material such as rice hulls to give rich hull ash (RHA), and the combusted biogenic silica may be subsequently treated to improve the filtration or adsorption properties thereof e.g. by changing the surface charge, the surface tension, the surface area, the average pore size, the pore size distribution, particle size distribution, and/or the permeability thereof. Such biogenic silica is useful to remove a species, such as an impurity, from a fluid to purify the fluid and/or to recover the species therefrom. RHA may be used to remove species including organic, inorganic or microbial particulates, surfactants, metal ions, non-metallic anions, organic compounds, color bodies, odor-producing species, chlorinated compound, pigment, free fatty acids, phospholipids, peroxides, oil and/or grease different from the non-aqueous fluid, algae, bacteria, and combinations thereof.
