Embodiment Construction
[0024] The technical solution of the present application will be described in detail below in conjunction with the accompanying drawings and specific embodiments. Wherein the same components are denoted by the same reference numerals. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to the directions in the drawings, and the words "inner" and "outer ” refer to directions towards or away from the geometric center of a particular part, respectively.
[0025] Aiming at solving the problem of missing and misdesignating the impact hazard area of the unbalanced spatial structure of the overlying residual coal seam, it is necessary to realize the precise division of the impact hazard area of the unbalanced spatial structure of the overlying residual coal seam. This embodiment provides a method for determining the impact risk area. This application can accurately determine the impact risk area of the...

The invention discloses an impact danger area determination method, a storage medium and electronic equipment, and the method comprises the steps: carrying out the pre-division of an impact danger area of a working face under the impact of an overlying coal seam residual mining imbalance structure before the stoping of the working face, and obtaining a pre-divided impact danger area; during working face stoping, dynamically dividing a working face impact dangerous area under the influence of the overlying coal seam residual mining unbalanced structure, and obtaining a dynamic impact dangerous area; and comparing the pre-divided impact dangerous area with the dynamic impact dangerous area to obtain a comparison result, and determining a final impact dangerous area according to the comparison result. According to the method, the impact dangerous area of the unbalanced space structure of the overlying residual coal seam can be accurately determined, targeted anti-impact measures are guided to be taken on site, the threat of rock burst disasters is reduced, and the safe and efficient mining technical level of a coal mine is improved.
Description
technical field [0001] The present application relates to the technical field of coal mine rock burst prevention and control, in particular to a method for determining a rock burst dangerous area, a storage medium and electronic equipment. Background technique [0002] In some coal mines in my country, due to historical mining reasons or unreasonable mining layout, the spatial structure of leftover coal pillars and overlying residual coal seams has been formed, which has seriously affected the mining of other coal seams. Studies have shown that many mines in my country have been affected by leftover coal pillars, The impact of the unbalanced spatial structure formed by the residual coal seam and the frequent occurrence of rock bursts have seriously affected mine safety and production, and have become problems that many mines have repeatedly encountered during the mining of multiple coal seams for a long time. [0003] It is generally believed that the area of unbalanced spa...
