چکیده
In this document, we will talk through information collected on all trends in mining the underground environment as much what happens world or new machinery America provides highest production mining. We often discover opportunities for improvement both productivity and costs. Of these methods, braking is not only most common, but also offers largest share of overall production, nearly 50 percent. These methods are determined by deposits economics therefore somewhat beyond control operator(Trends gold base metals | McKinsey, s. f.)

An Uncertainty-based Transition from Open Pit to Underground Mining
There are some large scale orebodies that extend from surface to the extreme depths of the ground. Such orebodies should be extracted by a combination of surface and underground mining methods. Economically, it is highly important to know the limit of upper and lower mining activities. This concern leads the mine designers to the transition problem, which is one of the most complicated problems...
متن کاملAutonomous Control of an Underground Mining Vehicle
This paper examines the kinematics and control of a Load Haul Dump Vehicle used in underground mining operations. The aim of the work is to develop an autonomous guidance strategy. A linear, state-space, mathematical model of the vehicle is derived purely from geometric consideration of the vehicle and its desired path. Autonomous regulation of the vehicle is shown to be theoretically feasible ...
