Abstract

In the process of coal mining, it is easy to cause geological disasters such as ground collapse, so as to reduce the loss caused by ground collapse, so it is necessary to evaluate the stability evaluation of the mining area and the prediction of ground collapse. Ground subsidence is affected by geological, hydrological and weather, the evaluation of ground subsidence based on multi-source information fusion, with the help of machine learning, data fusion, integrates geological exploration drilling data, coal mining data and hydrological data. Based on the mining area, this paper establishes the risk identification framework of 4 states, establishes the stability evaluation index system with 9 influencing factors, calculates the basic probability distribution of the indexes and distributes the information entropy, and finally integrates the probability distribution of the indexes. It provides a new feasible way for risk assessment of mine mining area.
