Specific features of a grinding module location in in-pit processing of peat raw materials

The article presents an analysis of a rational scheme for surface mining of peat raw materials using the in-pit crushing and conveying (IPCC) system for in-situ processing. Technologies for developing peat deposits are undergoing changes with the phased modernization of mining operations and related equipment, in line with the current trends towards increasing the efficiency of mining machinery and equipment for extracting and processing minerals. As a result of analyzing the in-pit processing system, it was established that there is a need to introduce a grinding module into the process of excavating peat raw material, thus revealing the benefits of in-pit processing. In accordance with the operational flow of raw materials in the technological scheme of the IPCC system, observing the principle of technological gap, it is proposed to unload excavated peat raw material into an intermediate storage area to ensure the operation of mining and processing equipment without having to coordinate their capacity. The placement of the grinding module along the extraction front, together with the movement of the intermediate dump, corresponds to a reduction in auxiliary operations time for moving the module. Due to this, a mobile design for the grinding module was determined due to the reduction in transportation distance of wet excavated raw peat materials with required off-road ability when moving on low bearing capacity grounds. In accordance with the mobile design of the module, a ski undercarriage has been selected, combining the advantages of stationary and mobile location methods inside the quarry.
