Embodiment 1
[0051] This embodiment provides a method for selecting the installation location of online ground pressure monitoring equipment in mines. The size of a mine is length (4283m) × width (3898m) × height (1473m), and the installation location of online ground pressure monitoring equipment is selected , including the following steps:
[0052] S1. The parameters of the historical mining process of the mine (the number of ore veins produced in the underground, the distribution of development projects, the mining sequence of the stope and the size of the stope) and the parameters of the mining status of the mine (the measured geological mid-section plan, the profile of the exploration line, the surface topographic map, longitudinal projection map of each vein and stope production ledger) for collection;
[0053] S2. According to the parameters of the mining status quo collected in step S1, the MIDAS GTS NX software is used to establish a three-dimensional mining model, which specifica...

The invention provides a method for selecting a mounting position of mine online ground pressure monitoring equipment, which comprises the following steps of: establishing a mine mining three-dimensional model according to parameters of a mine mining current situation, carrying out simulation calculation on the mine mining three-dimensional model by utilizing three-dimensional simulation analysis software, assigning physical and mechanical parameters of ore rocks in each region, and selecting a mounting position of the mine online ground pressure monitoring equipment. Performing simulated mining according to the parameters of the historical mining process of the mine to obtain underground stability parameter indexes of each mining stage, and finally selecting the mounting position of the online ground pressure monitoring equipment according to the stability parameter indexes; the selection principle is that the area stability is good, meanwhile, the area is close to the active area of the ground pressure activity, and effective detection and real-time monitoring can be carried out. According to the invention, the problem that the selection of the installation position of the current online ground pressure monitoring equipment lacks technical support is solved, the underground ground pressure activity change condition can be more effectively monitored, the purpose of forecasting and early warning the ground pressure activity is achieved, the safety of underground operating personnel and equipment is guaranteed, and the safety production of mines is realized.
Description
technical field [0001] The invention relates to the technical field of mine ground pressure monitoring, in particular to a method for selecting the installation position of online mine ground pressure monitoring equipment. Background technique [0002] In many mines at home and abroad, due to the large production capacity requirements and the late configuration of filling supporting equipment, many goafs have been formed underground; if the gobs are formed and cannot be filled in time, it will have a great impact on underground safety production. The resulting exposed space creates conditions for the movement of rock strata, and it is easy to generate shock waves that seriously threaten the safety of underground personnel and equipment. In order to achieve the overall goal of safe production in mines, an online ground pressure monitoring system must be installed in underground mines with a mining depth of more than 800m. Mining of non-coal mines occupies a very large propor...
