Automation of delineation of collapse-hazardous zones

The problem of critical deformations of ground surface above old mines is an urgent issue in most mining regions. The problem is particularly acute in the Donbas, where flooding of closed coal mines has led to redistribution of groundwater flow regime and induced cardinal change in the physical and mechanical parameters of enclosing rocks. As a consequence, the stress–strain transformation of rock mass results in activation and growth of processes of caving. Within the framework of knowledge-based mapping of collapse-hazardous zones in the city of Donets and forecasting of time and space parameters of caving propagation, a program module is developed for the automation of the collapse-hazardous zone delineation. The requirement of automaton of graphical constructions is governed by the abundance of underground excavations (around one thousand) which are situated in the area of the city and earlier had exits to ground surface. The module is made in C# in form of DLL library integratable in AutoDesk® AutoCAD®, and is meant for outlining of collapse-hazardous zones due to various mine excavations using parametric models and embedded geometrical data processing algorithms. The implemented accuracy analysis shows that the areas of zones outlined manually and using the program module disagree by no more than 1.6%. The program module enables detecting potential collapse hazard of a design underground excavation, calculating geometry of collapse-hazardous zones, mapping them on mining plans in the preset coordinates, as well as predicting time of critical deformations of ground surface.
