Comparative Research on Optimal Damping Matching of Seat System for an off-Highway Dump Truck

To protect the driver of off-highway dump trucks from the harmful vibration, this paper presents the comparison results to determine the optimal damping of the seat system by different optimization design plans. Three optimization schemes are considered including individually optimizing the damping of the cushion, individually optimizing the damping of the seat suspension, and integrately optim...

Coalbed Methane Canister Desorption Techniques

The British Columbia Geological Survey Branch and the Geological Survey of Canada have initiated ajoint project to assess the coalbed-methane potential of coal deposits in British Columbia. This project entails participation with private industry to obtain fresh coal samples for desorption from exploration projects throughout the province. Samples are collected from the drill site and undergo a...

Research of Coalbed Methane Development Well-Type Optimization Method Based on Unit Technical Cost

Coalbed Methane (CBM) is a high-quality unconventional energy resource. The successful development and utilization of a CBM resource needs to consider technical feasibility and economic viability. These factors are also necessary for the improvement of production safety in coal mines, reducing carbon emission, and optimizing energy structure. Because of its unique resource characteristics, surf...

Permeability Variation Models for Unsaturated Coalbed Methane Reservoirs

A large number of models have been established to describe permeability variation with the depletion of reservoir pressure to date. However, no attempt has been made to draw enough attention to the difference in the effect of various factors on permeability variation in different production stages of unsaturated CoalBed Methane (CBM) reservoirs. This paper summarizes the existing and common per...
