This paper proposes a method for dynamically controlling the working slope configuration in seasonal stripping open-pit coal mines. Constructing bench group model calculates cyclic advancement time of slope. A mathematical optimization is then established to minimize transport work overburden, and Sequential Quadratic Programming (SQP) algorithm employed solve it. The applied Shengli West No. 2 mine, results show that number benches 5. width 89 m, meets mining engineering continuity...
In this demo abstract, we describe an occupancy-based control (OBC) system under development that has potential to save 18% of the energy use on average in office buildings having single-duct variable-air-volume (VAV) heating, ventilating and air-conditioning systems. The OBC uses measured number occupants airflow rate through VAV box during times when no heating or cooling is called for by zone thermostat. It can be retrofit terminal boxes existing demonstration will provide: 1) background...
