ABSTRACT
The correct determination of the mining space exposed to water infiltration is one of the key issues for ensuring the safe operation of a mining facility. Modern technologies allow for the creation of a spatial model of mining excavations in the context of the deposit model and the aquifer level. This, in turn, allows for the precise determination of spatial distances between the hazard and the location of the workforce. The article introduces the concept of a dynamic model of the mining space, which enables continuous monitoring of the relative position of hazards in space, taking into account the impact of exploitation on the rock mass. The paper briefly discusses issues related to creating a spatial model of mining excavations, generating a numerical deposit model, considering the impact of exploitation on the rock mass, and determining the boundary of the potentially flooded area within the rock mass. It presents an algorithm for calculating the intersection of two surfaces, such as the aquifer level and the coal seam. The technology for automatically determining the distance between the workings and hazards, such as planned drilling holes, is also discussed.
