Abstract: Hydraulic fracturing is an effective technical means for the prevention and control of coal rock dynamic disasters such as rock burst, coal and gas outburst in coal mines. Hydraulic fracturing of coal and rock mass can induce a large number of weak microseismic signals. Aiming at the problems of microseismic signal identification and fracture location monitoring of hydraulic fracturing of coal and rock mass, the overall architecture of microseismic monitoring software for hydraulic fracturing of coal and rock mass was proposed. The microseismic monitoring software system for hydraulic fracturing of coal and rock mass in coal mine was designed and developed by using python language and Visual Studio Code editor. Based on engineering practice requirements, the software adopts modular design concept, including project management, parameter configuration, data call, data analysis and processing, three-dimensional visualization, event preservation and export function modules. The software interface is simple and easy to operate, which realizes the accurate identification of weak microseismic signals induced by hydraulic fracturing in coal and rock mass, the source location and source mechanism analysis of hydraulic fracturing. The spatial coordinates and source mechanism of hydraulic fracturing microseismic location events are visualized in three-dimensional, so as to dynamically depict the propagation process and spatial morphology of hydraulic fracturing in coal and rock mass. The research results provide effective technical means for the monitoring of hydraulic fracturing of coal and rock mass in coal mines, which is of great significance for the optimization design of hydraulic fracturing in the field.
