High Productivity Vacuum Blasting System
نویسنده
چکیده
In order to increase the productivity and economics of an existing (or baseline) vacuum blasting technology, which has been used to remove radioactive contamination, PCBs, and leadbased paint at Department of Energy (DOE) sites, the redevelopment and design of certain components has been initiated. These new components include a new rectangular blast nozzle, a blasthead with a wind curtain and sensors, and new dust separator. These have been designed and fabricated based on numerical estimated data derived by the development mathematical models. The mathematical models were validated by the experimental data with a deviation within ±10%. The experimental results indicated that the efficiency and economics of the redesigned blasting vacuum system with implementation of certain innovative components can be increased more than 50%.

In this work, a new drilling and blasting design methodology is introduced and applied at a case study mine to improve productivity. For the case study copper mine, a blast diameter of 203 mm is proposed to be used in the ore zone to meet the new required production rate of 90mtpa from 75mtpa. Currently, the Konya and Walter’s model is used to generate drilling and blasting design at a bl...

The conventional practice in open cut coal strip mining has been to blast the overburden or coal layers in separate blast events. This is done in order to maximise the benefits from throw blasting and also to limit coal losses. Each blast event usually has a particular design of hole diameters, burdens and spacings, explosive charges and blast timing in order to achieve the required blast outco...

Front row burden is one of the key parameter to improve the bench blasting results. Improper design of the front row burden can create nuisances in the form of ground vibration, flyrock, back break or it may responsible for breakage of improper fragment size from the rockmass. Therefore, front row burden need to be optimised on the basis of proper scientific assessment. It has been proved that ...

Grit blasting is a low cost surface modification treatment widely used to enhance mechanical fixation of implants through increasing their roughness. As a result of the severe surface plastic deformation, beneath the surface it produces additional effects such as grain size refinement, work hardening and compressive residual stresses, which are generally evaluated with destructive techniques. I...
