Embodiment Construction

[0149] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0150] 1. Determine the maximum value of the vertical downward impact (momentum) of the unit explosive on the formation after it explodes in the blast hole through experiments.

[0151] 2. On-site observation and control of various action quantities of landslides or relevant data used to calculate action quantities (such as charge amount, action quantity produced by unit explosives, rainfall, mine supply water flow), various affected areas, and simultaneous observation Landslide quality (or possible landslide quality), landslide angle, and landslide displacement. Before the landslide, the transparent sliding surface usually does not exist, and the corresponding landslide displacement does not exist, but the local de...

Abstract

The invention relates to a landslide prediction method of a strip mine, and belongs to the fields of basic theories, rock mechanics, explosion science and geological disaster prediction theories and application and researches thereof. The method mainly comprises the following steps that basic equations of landslide of the strip mine are established, and work direction, target, content and tasks are determined; action quantities which control landslide of the strip mine are measured; the relation between the virtual degree and action of a side slope of the strip mine is determined; the change rate of the virtual degree and the solid degree of the side slope of the strip mine is tested; and action research is carried out on the relation between explosion and landslide of the strip mine. The prediction method has the advantages that new theories of action landscape movement are established, quantified relational functions between landslide and explosion and other action and landslide are provided, breakthrough in research on landslide prediction science is made, landslide prediction is scientific and labor-saving, and the method is simple, practical, accurate and reliable.

Description

technical field [0001] The invention relates to a landslide prediction method in an open-pit mine, which belongs to the fields of basic theory, rock mechanics, blasting science, geological disaster prediction theory and application research. Background technique [0002] Landslides constitute a major disaster in the safe production of open-pit mines. Therefore, for a long time, people have attached great importance to the research on slope stability, prediction and prevention of landslide hazards in open-pit mines. At present, the methods of studying slope stability and predicting landslides in open-pit mines at home and abroad are as follows: 1. Engineering geological analogy method; 2. Structural analysis method; 3. Limit equilibrium analysis method; 4. Numerical analysis method, 5. Probability analysis method. Although these methods have been applied for a long period of time, due to the incomplete understanding of the relationship between action and change in traditiona...
