Surface Hard Rock Mining RAMJACK
Surface hard rock mining is often characterized by large faces and working areas, as well as the use of very heavy machinery to perform most of the core mining work. In this environment, instrument-based monitoring of the face and surrounding geological structures and control and monitoring of all vehicles and machinery are key management requirements to ensure a safe, productive and profitable mine.

[PDF] Analysis of Underground Block Caving Mining
The occurrence of the surface movement is the main focus of the study regarding to the gold & copper underground block caving mining in Papua, Indonesia. The underground mining has brought some environmental problems on the terrain surface such as the lowering of the elevation followed by growing of the waste pile as the result from the failure of the rock slope.
Surface subsidence due to underground mining
2015-6-1 In Indonesia, Ombilin coal mine had introduced a fully mechanized longwall mining system. However, the productivity is much lower than that expected. This is because of the dramatic change of coal seam conditions and unfixable face control. Prop and cap mining system has been introduced into the other underground coal mines as shown in Fig. 4. From the points of view of productivity, safety and economics, usual fully mechanized longwall mining system or room-and-pillar mining
