Operational Ground Control RockEng

Operational ground control plays a significant role in keeping mines safer and more productive. Operational Ground Control – The main purpose of operational ground control in a mining context is to ensure that all excavations made through rock and soil are kept safe and stable at all times (this practice can also sometimes be referred to by miners as slope management or strata control).

Sustainable Development of Mining Mineral Resources

Sustainable Development of Mining Mineral Resources

Jan 01, 2013 1. INTRODUCTION. The concept of sustainable development is now a widely used term in many areas of activity related to the life of man. It appeared in the second half of the twentieth century as a reaction to the dynamic economic growth seen in many countries around the world, which was often observed in conditions of excessively intensive and uncontrolled use of natural resources.

The Hard Rock Mining Bureau has separate programs for hard rock exploration and hard rock mining. Hard rock exploration requires a license to perform drilling and trenching and other activities to determine if an economical mineral resource is present. Hard rock mining can occur under a Small Miner Exclusion Statement (SMES) or under an ...

3 Technologies in Exploration Mining and Processing

The objective of ground control is to use site information and the principles of rock mechanics to engineer mine structures for designed purposes. Massive failures of pillars in underground mines, severe coal and rock bursts, open-pit slope failures, and roof and side falls all represent unexpected failures of the system to meet its design ...

The primary objective of a support system is to mobilize and conserve the inherent strength of the rock mass so that it becomes self-supporting. Rock support generally combines the effects of reinforcement, by such elements as dowels, tensioned rock
