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 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.
