COAL STUDY: Raven project one step closer

2010-10-11  BRITISH COLUMBIA A positive pre-feasibility study for the Raven underground coal project near Comox has been delivered to Compliance Energy Corp. of Vancouver.Pincock, Allen and Holt prepared the PFS.. Pre-construction capital expenditures are estimated at $240.1 million, with a further $32.0 million in sustaining capital.

A study of highwall mining panel stability

From published data on underground coal pillars, Zipf [21] proposed the following empirical Section 5 compared a FoS for a highwall mining panel and a PFS for the panel. There is a critical value of FoS of about 1.2, at which there is a sharp change in the curve of PFS versus FoS (see Fig. 8). This FoS of about 1.2 has been found to be the

Yancoal explores expansion potential at NSW coal

2019-4-18  Studies are underway to consider a potential underground mine at Mount Thorley Warkworth in the Hunter Valley, which could boost production by six million tonnes of run-of-mine (ROM) coal.

Major Mines & Projects Dartbrook Project

Within this Coal Resource, open cut mining is amenable in areas for a total of 1,803 Mt at a depth shallower than 450m. The OC PFS mine plan mines 226 Mt ROM coal with 190 Mt, or 84%, classified as a ROM Coal Reserve. Based on the modelled processing yield applied by the Competent Person and rounding, this equates to a Marketable Reserve of 140 Mt.

Search results for: underground coal gasification

It is an inherent clean coal technology as it avoids ash disposal, mining, transportation and storage problems. Gasification of underground coal using steam as a gasifying medium is not an easy process because sending superheated steam to deep underground coal leads to major transportation difficulties and cost effective.
