A Collision Detection-Based Wandering Method for Equipment Deploy Scene in Land Reclamation Area of Mining Dump
نویسندگان
چکیده
Aiming at developing a simple and efficient collision detection method to support the wandering in equipment deploy scene in land reclamation area of mining dump. This paper presents an efficient algorithm for collision detection in the waste dump land reclamation equipment deploy scene using a bounding volume nestification which consists of an oriented bounding boxes (OBBs) enhanced with axially aligned bounding boxes (AABBs). This approach combines the compactness of OBBs and the simplicity of AABBs. The majority of distant objects are separated using the simpler AABB tests. The remaining objects are in close proximity, where OBBs test is needed to detect. Implementation results show that our algorithm achieves considerable speedup

Optimization of Concurrent Mining and Reclamation Plans for Single Coal Seam – a Case Study in Northern Anhui, China
Abstract: The extraction of underground ore body inevitably causes a large amount of land subsidence. Current reclamation technologies in China mainly focus on stable subsided land. Therefore, a new technology for reclaiming unstable subsiding land is being studied for restoring farmland as much as possible based on a case study in Northern Anhui, China. In consideration of the mining plan, sub...
متن کاملA new developed model to determine waste dump site selection in open pit mines: An approach to minimize haul road construction cost
Today, during the life of an open pit mine, million tons of materials, including waste and ore, are displacing by truck fleets. In the case of a shallow ore deposit, which is located up to 300 meters to the ground surface, depending on preliminary equipment size and capacity, it will take three to five years to remove overburden and waste rocks to expose the ore body. In that period, the main w...
متن کاملEffects of Sandy Desertified Land Reclamation on Soil Carbon Sequestration (Key Study: Kerman province)
Desertification leads to decrease in the ecosystem C pool and attendant reduction in Soil Organic Carbon (SOC). Reclamation of sandy land in arid and semi-arid has a high potential to increase carbon sequestration and improving soil quality. Our objective as to examine the changes in the soil carbon sequestration and soil properties of two soil layers (0–20 and 20-50 cm) under two types of recl...

That is the daily challenge for the operators of the giant dump trucks used in surface mines. As a result, each year, an average of 20 accidents and three fatalities occur involving collisions between a piece of surface mining haulage equipment and either a smaller vehicle, a worker, or some other object. Another 21 accidents occur and three mining equipment operators are killed each year when ...

Possibility of mapping the distribution of Arsenic and Chromium in a mining area was investigated using combination of (VNIR) reflectance spectroscopy and geostatistical analysis. Fifty five soil samples were gathered from a waste dump at Sarcheshmeh copper mine and VNIR reflectance spectra were measured in a laboratory. Savitzky- Golay first derivative was used as the main pre-processing metho...
