Programmable Mining Control

PMC-R 2.0

The HBT PMC-R 2.0 system represents the next-generation, state-of-the-art HBT automated control unit for longwall roof support applications. Based on the successful predecessor PMC-R, it combines the best features of that system with additional features required by longwall operations. The result is an innovative electrohydraulic shield control contributing to full automation of the advancing longwall.

Application

The intrinsically safe PMC-R 2.0 control units are specifically designed to be used on shearer or plow faces to provide high levels of longwall automation.

Each roof support is equipped with one PMC-R 2.0 control unit and solenoid driver to operate the in-shield hydraulic functions and peripheral components, such as sensors for cylinder pressure and stroke length, shield inclination and personnel proximity detection.

The PMC-R 2.0 unit controls and displays all functions of a roof support and serves as the interface between operator and machine (HMI).

Enhanced Communication

More Computing Power

Increased Usability and Serviceability

Interactivity

This interactive system allows users to execute single shield and automatic functions, as well as perform remote control operations from anywhere in the mine, including the surface. To provide feedback for the operator on the longwall, important process values are continuously displayed on a full-color display.

High-Speed Data Transmission

The PMC-R 2.0 control unit delivers fast 100M/Bit Ethernet communication, enabling real-time system feedback and data refresh rates for remote control operation.
The low latency connection also means process data values are updated much faster for higher resolution when data logging and reviewing historical trending. An enhanced user experience is provided when viewing 3D VSoftware applications as the data is refreshed at a higher frequency, resulting in a smoother and more accurate representation of the equipment underground.

Advanced Functionalities

The high bandwidth connection enhances machine-to-machine integration, which provides for advanced automation functionality. More complex messages can be exchanged between the equipment, creating holistic integration and interoperability for increased performance and reliability.
