Caterpillar Global Mining displayed a range of advanced technologies at the Longwall USA event from 11-13 June. Centre stage was a preview of the newest Cat shearer model, the EL 1000, designed specifically for low and medium-height seams. Currently in development, Cat states that the EL 1000 will add depth to the already expansive Caterpillar range and will offer a precisely designed system with the power, production potential, controllability and safety features required to address future demands and varying geological conditions in this segment.

Preliminary specifications for the EL 1000 shearer indicate that the new model will accommodate seam heights from 1.6 to 3.2 m, will deliver an estimated cutting power of 1,000 kW, and will provide haulage power on the order of 2 x 100 kW. Reflecting the basic design of proven Cat longwall shearers, the EL 1000 will feature massive, one-piece-mainframe construction, exchangeable modular components, advanced automation, and Ethernet communication. Cat states: “As with all Cat Global Mining products, the worldwide network of Cat dealers will add significant value to the EL 1000, ensuring the highest quality product support—replacement parts, competent timely service and industry expertise. Cat dealers understand longwall operators’ needs for reliable, continuously high production, and they have the capabilities to help accomplish that goal.”

Integrated with the Cat PMC-R electro-hydraulic roof-support control system, which is built to reliably identify the presence of personnel in longwall faces through RFID (Radio Frequency Identification), the Detect Personnel system is designed to avoid contact between personnel and moving equipment by monitoring safety zones and access authorisation. A demonstration of system capabilities was also featured as part of the Cat display. The display also features a virtual-reality, three-dimensional presentation of the Cat MineStar System Operations Centre, depicting an operating mine.
