摘要
A method for initiating combustion in a subterranean carbonaceous deposit by positioning at least two wellbores from the surface into the subterranean deposit; extending a first borehole substantially horizontally from a first wellbore into the vicinity of a second wellbore; extending a second borehole substantially horizontally from a second wellbore into the vicinity of the first wellbore; positioning an explosive charge in at least one of the boreholes; detonating the explosive charge to produce a rubblized zone between the first wellbore and the second wellbore; injecting a free-oxygen containing gas into the carbonaceous deposit through one of the wellbores; and igniting the carbonaceous deposit at one of the wellbores.
