The Use of a Roadheader Simulator in Research of Dynamics and Energy-Consumption of Excavating Underground Roadways and Tunnels

Boom-type roadheaders are commonly used for excavation of roadways in underground mines, tunnels, and other architectural structures using trenchless techniques, as well sinking shafts occasionally excavating the harder soil softer formations cut cover construction. The main research development these machines is to offer solutions automatic control. This refers automation or robotization operation, raises possibility their eventual unmanned operation. article presents a roadheader simulator which implements experimentally verified mathematical models describing dynamics operation rock cutting process. Due very high computational requirements, distributed system comprising several workstations connected via TCP/IP was used. Both visualization heading face graphic simulation course rock-cutting process were carried out Autodesk Inventor Professional 2022 graphics engine. It provided with virtual scene environment enabled control model’s movement during simulated process, including generation breakout while drilling roadway tunnel. presented enables determination various time characteristics, example, dynamic loads, power demand, efficiency, energy consumption, others. still under development.
