Problems solved by technology

[0004] (1) The existing hazard identification methods consider the natural attributes of the disaster itself when identifying the hazards of mine disasters, but do not consider the social attributes of the potential total loss that may be caused after the disaster occurs
[0005] (2) Among the identification and evaluation methods of natural disaster hazards in mines, the theoretical and systematic nature of the expert scoring method is still lacking, and sometimes it is difficult to guarantee the objectivity and accuracy of the evaluation results
[0006] (3) The occurrence mechanism of natural disasters in mines is relatively complex, which increases the complexity of identifying and evaluating hazard sources

Embodiment 1

[0160] Embodiment 1: Physical model dynamic evolution test analysis

[0161] 1. Model test design

[0162] 1.1 Test steps

[0163] The essence of the open-pit mining slope similarity model test is to use materials with similar mechanical properties to the prototype geotechnical materials to construct a model according to the set geometric similarity constants, and to simulate ore body mining and other working conditions on the model. Therefore, the selection of model test materials and the determination of the test plan are the key factors of the test. Focusing on these two aspects, this test mainly includes the following aspects:

[0164] (1) Determination of the prototype rock and soil parameters; the physical and mechanical parameters of the slope rock and soil mass are the basis of all analysis of the research object, and are also important theoretical parameters for the design of slope support. Therefore, in-situ tests and indoor rock block tests were carried out on the...

[0294] Example 2: Stability Analysis of Open-pit Mine Slope Excavation

[0295] Using FLAC 3D The evolution law of the stratified high and steep slope of Jianshan Phosphate Mine during mining activities is analyzed and studied.

[0296] Using FLAC 3D When carrying out computer numerical simulation, first establish the finite difference grid, determine the physical and mechanical parameters of the material and the constitutive model of the material, and specify the boundary conditions and initial conditions of the calculation model. The finite difference grid is used to define the result shape of the analysis model; the properties of the material and the corresponding constitutive model are used to characterize the mechanical response of the model under external forces; the boundary and initial conditions are used to define the initial state of the model. After completing the preparatory work for the above simulation, the initial state of the model can be solved, the excavati...

[0323] Embodiment 3: Slope Stability Control Technology

[0324]The ultimate goal of slope stability analysis and evaluation is to propose scientific, reasonable, and operable treatment technical solutions based on slope stability conditions to control slope landslide disasters, so as to achieve the purpose of disaster prevention and mitigation.

[0325] 1. Technical Analysis of Slope Stability Control in Open Pit Mine

[0326] The slope stability of open-pit mines is a major problem that affects and plagues mine production and safety. Compared with other slope engineering, open-pit mine slope has the following characteristics: With the different stages of mine production, the understanding of the stability of open-pit mine slope is gradually deepened. Figure 13 It is a block diagram of dynamic research on slope stability and control technology in open-pit mines.

Description

technical field [0001] The invention belongs to the technical field of mine natural disaster information management, and in particular relates to a risk prevention mechanism management system and method for mine natural disaster hazard sources. Background technique [0002] At present, mineral resources are an important material basis for the development of human society. With the rapid development of economy and the acceleration of social urbanization, the consumption of various mineral resources in human society is increasing rapidly, resulting in the development and utilization of mineral resources. faster. In the past 100 years in the 20th century, the world has consumed 265 billion tons of coal, 142 billion tons of oil, 38 billion tons of iron (steel), 760 million tons of aluminum, 480 million tons of copper and 78 trillion cubic meters of natural gas and other minerals. resource. In the 21st century, due to the new round of industrialization and population growth in ...
