Embodiment Construction

[0054] like figure 1 A simulation evaluation method for human damage caused by mine gas explosion shock waves is shown, including the following steps:

[0055] Step 1, establishment of fluid domain model: using data processing equipment and calling three-dimensional modeling software to establish a fluid domain model, the fluid domain model is a three-dimensional grid model of the mine to be evaluated;

[0056] The mine to be evaluated is an underground coal mine roadway, and the mine to be evaluated is divided into two roadway sections; the roadway section with gas in the mine to be evaluated is a gas roadway section, and the other roadway section is an air roadway section; The three-dimensional grid model of the mine to be evaluated is composed of a gas tunnel section model 1 and an air tunnel section model 2, the gas tunnel section model 1 is the three-dimensional grid model of the gas tunnel section, and the air tunnel section model 2 is The three-dimensional mesh model o...

Abstract

The invention discloses a simulation evaluation method for human body injury by mine gas explosive shock wave. The method comprises the following steps: firstly, fluid domain model building: the built fluid domain model is a three-dimensional mesh model of a to-be-evaluated mine, and the to-be-evaluated mine is divided into a gas roadway section and an air roadway section; secondly, fluid-solid coupled model building; thirdly, human body damage failure evaluation: 301, evaluation position setting; 302, human body model adding; 303, fluid and solid coupling numerical computation; 304, human body damage failure evaluation; 305, human body damage failure evaluation in a next position; 306, repetition of the step 305 till the accomplishment of human body damage failure state evaluation processes in various different evaluation positions in the fluid domain model. The method is simple in steps, reasonable in design, convenient to realize and good in use effect, and performs simple, efficient and accurate evaluation on human body damage failure by the mine explosive shock wave according to the fluid and solid coupling effect of the explosive shock wave and a human body.

Description

technical field [0001] The invention belongs to the technical field of coal mine safety assessment, and in particular relates to a simulation assessment method for human damage caused by mine gas explosion shock waves. Background technique [0002] Coal is my country's main energy source, accounting for about 60% of my country's primary energy production and consumption structure. Since coal mining, my country's coal mine safety situation is very severe, mine fires, flooding accidents, gas and coal dust explosion accidents have occurred one after another. However, coal mine gas and dust explosion accidents account for more than 50%, and there are many factors affecting coal mine gas and dust explosion, which have the characteristics of potentiality, suddenness, destructiveness and catastrophe. Since the founding of New China, there have been 24 accidents in which more than 100 people died at one time in coal mines across the country, 21 of which were gas (coal dust) explosi...
