In Suichang gold mine, the altered rock type deposits were cut by faults and joint fissures, leading to complex resource endowment characteristics, large changes in occurrence, a serious of ore vein branches great difficulty mining. order select suitable mining method for such difficult complicated orebody, multi-factor multi-index comprehensive evaluation system involving benefits, costs, safety other aspects was constructed using Pythagorean fuzzy sets TOPSIS method. Taking mine as an...
In the mining industry, with numerical simulation analysis of stope roof stability, exposed area computation, and pillar buckling collapse simulation, backfill body creep damage mechanism research is becoming most popular method in field techniques. this paper, we first summarized analyzed current application status existing problems for solving engineering technical problems; then, based on practical phosphate rock resources under high steep slopes (HSRS), carried out a true-3D study...
Despite China’s position as a global mining powerhouse, tens of thousands small- and medium-sized mines (SM mines) within the country continue to pose potential safety hazards environmental pollution risks. Only through identification suitable development paths can these improve their economic benefits, ultimately driving significant progress in industry. Backfill mining, an environmentally friendly method, has emerged viable solution, offering ensure safety, reduce stemming from tailings...
The mining of layered soft bauxite under coal seams (BCS) will cause serious underground goaf disasters and surface Bayer process red mud (BRM) pollution. In order to realize the safe efficient BCS, feasibility recycling BRM as a backfilling aggregate was explored. A series tests were conducted prevent pollution diversion from storage goafs, numerical simulation analysis carried out based on FLAC3D protect overlying seam. results show that: action encapsulation, solidification inhibiting...
The stability of mine slopes is an important factor influencing the orderly production mines and safety people’s lives property. can be effectively determined by means three-dimensional simulation analysis. Some 3D analysis methods are based on 2D analysis, still essentially methods, whereas this digital uses a true method. This method reflect overall slope in more realistic way, at same time, situation selected sections observed, making scientific rigorous. study takes Shizhuyuan Nonferrous...
The stability of high and steep slopes in open-pit mines is closely related to the mine operations lives surrounding residents, so it important ensure safety slopes. Hazard classification analysis under different working conditions are studied using Shizhuyuan non-ferrous metal from underground mining as a typical example. Firstly, data on rock mechanics parameters were obtained through site investigation sampling. Then, slope model was established some selected for qualitative quantitative...
To extract the 6.3 million tons of high‐quality phosphate resources, a stability analysis and confidence level evaluation backfill mining under high steep rock slopes (HSRS) were conducted using Slide software Monte Carlo simulation. The geological model HSRS was constructed based on geotechnical investigation. A series laboratory tests to obtain engineering parameters mass, mechanism action method analyzed. After analysis, average safety factors for normal operation are 1.575 (backfill...
Tailings concentration is indispensable for backfilling. Additionally, the residual flocculants in process affect rheological properties of ultra-fine argillaceous backfilling slurry (e.g., viscosity and yield stress), resulting a great effect on fluidity resistance pipeline transportation. In this study, to explore residue slurry, series tests (constant shear rate test variable test) were performed by changing type, dosage, stirring time, temperature addition amount binder added. The...
<title>Abstract</title> For many years, the lead-zinc mine of Suichang Gold Mine has been mined by segmented open-field method, and mining above 500 m basically completed, forming a high-stage large-span columnar goaf group, which is very easy to produce roof fall, slope fragmentation instability collapse, then leading large-scale ground pressure disasters, causing surface subsidence endangering safety operations deep untouched ore bodies. In order better discuss stability goaf, Flac3D used...
Aiming at the existing problems of low efficiency, lagging monitoring results, and poor reliability accuracy in present roadway roof separation system, a high-precision Fiber Bragg Grating (FBG) indicator is designed through theoretical analysis, numerical simulation, laboratory tests—according to fiber grating sensing principle. Based on Microsoft. Net platform, C# programming language, VS2010 integrated development tools, corresponding on-line software developed. On this basis, real-time...
