Steeply dipping coal mines typically deal with geologically complex deposits with a large number of seams with thicknesses that vary significantly. They require highly selective mining techniques along the seam boundaries and pose several challenges not typically faced in traditional open-cut coal mines. SCS has been specifically designed for mines with steep coal seams that rely on terrace mining techniques.

SCS is 100% script-free and made up of pre-defined logic, which, when combined with the knowledge of mining engineers, automatically determines what is practically possible to achieve across one or multiple mining operations. This agility gives engineers the ability to respond rapidly to the market and maximise output, delivering shareholder value.

Redefining mine planning and scheduling

Underpinning RPM’s Steep Coal Solution (SCS) is a powerful scheduling engine that does all the heavy lifting without compromising sophistication and capabilities. From an individual site through to multi-site and global operations, the parametric approach adopted by SCS means engineers can amplify their decision-making process. This embedded intelligence, together with our intuitive user interface, increases mine productivity and provides rapid ROI with a solution that is scalable, intuitive and fast to learn. SDCS is the only Enterprise Planning solution that complies with industry standards and aligns with ISA-95 delivering true collaboration across the mining value chain.

Process-driven with practical scheduling rules

SCS uses a process-driven workflow to guide the user. It is 100% script-free, fast to implement and even faster to learn. The mining rules, targets and objectives used to control the schedule have been tailored for terrace mines extracting steep coal seams. The sequential steps that form the scheduling process eliminate the need for complicated scripting (and costly consultants to write them). Rather than complex menus and options hidden within deeply nested dialogues, the repeatable scheduling process provides every option exactly when and where required.

Automatically schedule reserves

With SCS, the process of generating the scheduling database is fully automated. It reads geological data directly from grids and generates detailed 3D solids of every seam intersecting each bench. The task is performed rapidly, even with massive geological models.

Dynamic haulage modelling

The ability to capitalise on opportunities for backfilling in worked out sections of the mine is essential for scheduling terrace mines. With SCS, the dumping of waste (in-pit and ex-pit) is scheduled at the same time as the mining, so it is able to identify the optimum waste dumping strategy throughout the schedule. SDCS is the only scheduling solution capable of scheduling mining and filling simultaneously to optimise the mine’s waste placement strategy.

Integrated Product Optimiser

Automatically find the best way to wash, process, blend and stockpile coal to maximise the value of one or more products. SCS is the only scheduling solution capable of optimising complex alternative options. And because it does this at the same time as it builds the schedule, rather than as an afterthought, it ensures the optimal mining decisions are taken every period and users are able to identify the most cost-effective scheduling and extraction sequence whilst still hitting their product targets.
