摘要： The present invention discloses a strip support method by using a filler and residual coal pillar in an irregular goaf, including the following steps: step 1: determining a treatment area of an irregular goaf according to a boundary angle by using a to-be-built architectural complex as a protection object; step 2: arranging multiple grouting and filling strips in the treatment area at intervals along a strike direction or a dip direction of a coal seam, where the grouting and filling strip is of a strip shape; and step 3: conducting grouting in positions of the grouting and filling strips by using a grouting device, where a filler formed by grouting and coal pillars in the irregular goaf jointly form a structural support. A grouting and filling method for an irregular goaf in the prior art has high treatment costs and cannot eliminate a hidden hazard that the ground surface suddenly subsides suddenly due to instability of coal pillars to ensure a subsidence reducing effect. The grouting and filling method for an irregular goaf in the present invention can effectively resolve the problem mentioned above.

摘要： A pore structure three-dimensional model (101) and a method for fabricating the same, an experiment system and a transparent experiment method for replicating fluid displacement process within a pore structure of a natural rock mass are provided. A structure image of the natural rock mass is acquired by using computed tomography scan technology or imaging technology. The structure image includes pore structure information of the natural rock mass. By using an image processing method, the pore structure information in the structure image is extracted and a digital structure model corresponding to the natural rock mass is reconstructed. Based on the digital structure model, a transparent and visible three-dimensional pore structure model (101) is printed by using 3D printing technology, such that a pore structure (1011a) inside the natural rock mass is visible. Therefore, flow phenomenon of fluid when performing displacement-seepage inside the rock mass can be observed in a process of experiment. Images of seepage can be rapidly captured by a camera (1051) outside the model. Further, temperature, flow rate, and pressure of components can be accurately controlled, to achieve accurate replication in various experiment conditions, so as to visually display an immiscible displacement-seepage whole process occurs in a complex pore structure inside the natural rock mass and quantitatively analyze distribution features of a seepage field and a speed field of immiscible displacement.

摘要： A mine field layout method suitable for fluidized mining of coal resources is provided. A main shaft and an air shaft are provided in the mine field, the bottom of the main shaft is located in the shallow horizontal coal seam zone, and the bottom of the air shaft is located in the deep horizontal coal seam zone. The horizontal main roadways are arranged at two boundaries along the strike of the coal seam, and inclined main roadways are arranged at two boundaries along the dip direction of the coal seam. Connecting roadways are located inside the mine field and are in communication with the horizontal main roadways. In the coal mining stage, the coal resources can be converted into the fluidized energy product and/or electricity by an unmanned automatic mining machine. The energy transmission pipelines arranged in the main shaft and the roadways transport the fluidized energy product and/or the electricity to the ground. This mine field layout reduces the number of shafts and roadways for coal lifting, transportation, drainage, ventilation, and power supply. Therefore, the construction and maintenance costs of the roadway are reduced. In addition, there is basically no residual coal pillar left in the mine, and the recovery ratio is high.
