Abstract

The invention provides a suspended roof goaf danger assessment method and device, a storage medium and a program product. The method comprises the steps that the coal pillar stability safety coefficient of a target suspended roof goaf is determined; based on the coal pillar stability safety coefficient, the collapse possibility of the target suspended roof goaf is determined; determining the collapse harmfulness of the target suspended roof goaf; and based on the collapse possibility and the collapse harmfulness, determining the risk of the target suspended roof goaf. The method not only considers the possibility of the collapse of the suspended roof goaf, but also considers the harmfulness of the collapse of the suspended roof goaf, so that the danger of the suspended roof goaf is more accurately and scientifically analyzed and obtained, the scientific assessment of the danger of the suspended roof goaf is realized, and the accuracy of the danger assessment of the suspended roof goaf is improved.

Description

technical field [0001] The invention relates to the technical field of coal mining, in particular to a risk assessment method, equipment, storage medium and program product of a goaf with a suspended roof. Background technique [0002] The suspended roof goaf includes room-pillar goaf and strip goaf, and the mining area, mining technology, and mining size of the room-pillar goaf and strip goaf are different. When the coal room or strip is mined, the stress state of the coal pillar and the roof changes. As time goes by, some coal pillars become unstable, causing the roof of the goaf to collapse, and a considerable area of ​​the goaf Under the support of coal pillars, it has not collapsed for a long time, forming a suspended roof goaf. [0003] Once the remaining coal pillars in the goaf of the suspended roof lose stability, it will cause shocks, hurricanes and rapid subsidence of the surface, which will pose a serious threat to underground safety production, ground ancillary...
