Left: Entry point to the new drift with the quarry in the background. (Foto: staff of consortium) Available resources and equipment This outstanding performance was achieved by a mixed team representing both JV partners, whose Members were soon working as a close-knit unit. Some of the drivage work was undertaken using the multiple-entry system with a team of between 13 and 17 men. The heading crew was supported by some very effective equipment, comprising the AC 352 S twin-arm drill jumbo from the Gehren project, which was used for drilling the shotholes and rockbolting holes and installing the weldmesh screens, an ITC 312 H3 Schaeff excavator for loading and salvage work and two Terex TA 30 dumper trucks for haulage duties between the intermediate stores and the tunnel portal. As well as ventilation equipment, a compressor and a shotcrete supply bin the operation was also supported by a Komatsu WA 470 loader with a payload capacity of 4.2 m 3 and a Merlo P30.13 telescoping forklift.

(Foto: staff of consortium) These performance levels could not have been attained without some terrific support and cooperation from the client. We would therefore like to take this opportunity to express our appreciation for this back-up and for the hospitality served up in the form of pretzels at our regular meetings. As well as providing site supervision the client was also responsible for mine planning approvals, rescue services and project planning. The client’s satisfaction with the quality of the mining activities and support measures was borne out by the fact that the JV was awarded a follow-up contract for the complete electrification of the mine. This work essentially comprised the installation of a transformer room and the electrification of all lighting, underground fans, crusher and conveyors.

The future All work was successfully completed and the new mine infrastructure was handed over to the client right on time for the start-up of the new lime kiln in April 2009. Output from the surface quarry can now be scaled down – to be replaced by production from the new underground workings. At this point we would like to wish Märker Kalk Marbled lime and what it can become to the drill steel.

(Foto: staff of consortium) GmbH every success in its new venture along with a rapid upsurge in market demand. Schachtbau Nordhausen GmbH and Thyssen Schachtbau GmbH also hope that the Gehren barytes mine will see raw-materials prices stabilising again and that the operators will have the entrepreneurial courage to continue the process that commenced with the underground development work.
