Abstract: The invention relates to the technology of rib spalling. In the present invention, adjacent support anchors are tightly connected with each other by anchor cables; each of the support anchors are at least connected with an anchor cable tightly extending from four different directions, so that each of the anchor cables constitutes a mesh structure, and a flexible gap corresponding to the thickness of the support anchor is formed between the inner flexible support net and the outer support net at the anchor cable, which not only allows the support anchor to tighten an anchor bolt, but also makes the anchor bolt in the entire region form a whole.

Abstract: A method for quickly optimizing key mining parameters of an outburst coal seam as provided includes steps of constructing a graphic basic information model of the coal mine, giving coal mine characteristic information, performing mining simulation, constructing a CNN-LSTM predicating model, obtaining changes under different mining conditions, constructing a Lorenz chaotic primer, and the like. The model can be improved with continuous breakthroughs in theory, so that the model has a strong learning ability and can adapt to the constantly changing complex geological environment. The method has very good predictability for the determination of coal seam group parameters, and can efficiently select and output a set of candidate parameters.

Abstract: A method for rapidly acquiring multi-field response of mining-induced coal rock is provided. Based on 3D printing, the method achieves the control of material deformation and turns from 3D to 4D, thus saving manpower and material resources; further, repeated experiments may still be carried out under approximately the same conditions after each printing, so that the similarity of similarity simulations is greatly improved and a stable and reliable scientific law is conveniently obtained; besides, a BP neural network model may be built based on the data collected from similarity simulations to rapidly acquire an accurate and real coal seam mining response.
