An Improved Model for Prediction of PM10 from Surface Mining Operations
… quality permits. Past research has shown that haul trucks create the majority (80-90%) of PM10 emissions from surface mining operations. Therefore, this research concentrated on improving the ISC3 model by focusing on modeling PM10 emissions from mobile sources, specifically haul trucks at …

Driving the Future of Long-Haul Trucking: Realizing the Potential of Battery Electric Vehicles through an Analysis of Financial and Environmental Impacts
… to battery electric vehicles (BEVs) for long-haul trucking, using system dynamics modeling, financial impact modeling, and environmental impact modeling, and looks across a broad range of possible future scenarios that could impact the viability of BEV use in long-haul trucks. System dynamics …

Optimization of Quarry Operations and Maintenance Schedules
… Edge to analyze the performance of loaders and haul trucks. This data consists of performance metrics such as truck and loader cycle time, payload per loader bucket, total truck payload, truck plan distance, and loader dipper count. This study uses data analysis and machine learning techniques …

Instrumentation and Dynamic Characterization of the Galena Creek Bridge
… Live loading through the use of construction haul trucks produced excitation in the vertical direction. An eccentric mass shaker was then used to excite the bridge transversely. Acceleration data collected from these experiments was compared to predictions from analytical models built for the …

The role of natural gas as a vehicle transportation fuel
… fleet vehicles and in heavy-duty, short-haul fleet vehicles. For light-duty applications, there is a need to address an existing market barrier in the US by reducing the incremental cost and improving the vehicle performance of CNG vehicles to levels found in Europe. This incremental cost …

Data Quality of Fleet Management Systems in Open Pit Mining: Issues and Impacts on Key Performance Indicators for Haul Truck Fleets
… two different software vendors. For each FMS, haul truck fleet data from a separate mine site was analyzed. Both mine sites had similar haul trucks, and similar fleet sizes. From a qualitative perspective, it was observed that inconsistent labelling (assignment) of activities to time categories …

EVALUATING MINE SOIL PREPARED BY SCRAPER PANS FOR HERBACEOUS PLANTS AND PINE SEEDLINGS AT AN EAST TEXAS LIGNITE SURFACE MINE
… Oak Hill Mine in east Texas. The conventional haulback or ‘truck shovel’ reclamation method uses haul trucks for the selective transport and placement of oxidized overburden to serve as the reforestation growth medium. Transport and placement of overburden can also be accomplished using scraper …

Quantifying the Environmental Performance of a Stream Habitat Improvement Project
… fuel combustion in heavy equipment and haul trucks by ensuring clear access to the channel and streambank, using small engine equipment to clear access corridors during site preparation, running more fuel-efficient machinery or bio-fuel powered machinery, and by attempting to minimize …

Evaluation of Existing Subsurface Cooling Systems Worldwide and Development of Efficient Cooling Methods and Systems Based on Renewable Energy Sources
… surface mining perspective is to use very large haul trucks bringing ore up a long ramp system which daylights in the open pit. This type of ramp mine access drift is driven into the most stable strata surrounding the open pit. This mining arrangement is the proposed application for bulk air …
