    Apr 01, 2016 Higher powder factor causes oversize and lower powder factor results in crushed rock. Mean fragment size was plotted against the powder factor for 91 blasts of coal overlying overburden benches, as presented in Fig. 22. The general trend shows that, with increase in powder factor, the mean fragment size decreases..The swelling, interactions of gases within the coal matrix and the resultant changes in the permeability, sorption, gas flow mechanics in the reservoir, and stress state of the coal can impact a number of reservoir-related factors. These include effective

    found in the surface coal mines of WV generally the majority of the state excluding the eastern panhandle are sandstone and shale WVGES 2011. Properties such as bank and loose densities, unconned compressive strength UCS, abrasivity expressed through Cerchar Abrasive Index CAI, seismic wave velocity, and swell factor are.Jun 26, 2011 The coal samples were vacuum dried before each test, then saturated by a test gas until steady state was reached. Measurements of adsorption, swelling strain, elastic stiffness, creep strain and permeability of both intact and crushed samples were carried out at a series of either increasing pore pressure or increasing effective stress.

    This project aims to investigate the parameters that affect the swell factor used in design and reported volumes for different parts of the mining process and cast blasting methods at various locations around Callide mine. The Callide coal mine along with most mines worldwide have been using a swell factor as a variable in open cut mine design and volume removed calculations throughout history..At Callide coal mine a swell factor with now unknown origins or validity is being used. The current swell factor appears to be correct which can be seen by design being achieved however, after the annual Audit by Anglo BCO, the validity of this figure has been requested. As well as validating the swell factor
