Description
Technical Field
The invention belongs to the field of coal mine safety, relates to coal mine hydrogen sulfide disaster risk judgment, and particularly relates to a comprehensive judgment method for hydrogen sulfide disaster risk of a waste oil well in a coal mining area.
Background
Mineral resources such as coal, petroleum, natural gas and the like in the Erdos basin are quite rich, but due to the influence of geological structures, resources such as coal, petroleum, natural gas and the like coexist, and shallow coal and deep oil and gas resource exploitation are projected and overlapped in a three-dimensional way, so that the resource overlapping exploitation is caused to influence each other. After the development of the early petroleum well, the abandoned oil well left in the resource overlapping area not only increases the difficulty of coal mining design and causes the waste of coal resources, but also has great potential safety hazards for the mining of the adjacent coal seam of the petroleum well, and once the mining roadway approaches the influence area of the abandoned oil well, the great potential safety hazards of water, gas, oil and the like rushing into the working face exist. Because the abandoned oil well is an open hole well or a finished well is damaged due to formation deformation, rust, corrosion and the like of an oil well sleeve, a large amount of oil gas in the oil well, particularly toxic and harmful gases such as hydrogen sulfide and the like, gradually invade a coal measure stratum through the abandoned oil well, and serious harm is brought to physical and mental health of underground operators and mine safety production.
Hydrogen sulfide is the main toxic and harmful gas in the exploitation process of oil and gas fields and also in the exploitation process of coal mines. Hydrogen sulfide has severe toxicity, and has relatively great harm, especially to human body. Aiming at serious threat of the coal mine hydrogen sulfide disaster, research on the aspect of coal mine hydrogen sulfide disaster treatment is developed at home and abroad, and real-time monitoring of hydrogen sulfide gas gushing during mining of a working face is realized, but the danger and dangerous area of the hydrogen sulfide disaster cannot be judged before mining, and larger blindness and passivity are brought to the control of the coal mine hydrogen sulfide disaster. How to provide an effective and feasible hydrogen sulfide disaster advanced judging and identifying method is a problem to be solved urgently.
