Coal
Coal-fired electricity at an all-time high Global coal-fired generation reached an all-time high in 2021, pushing CO2 emissions from coal power plants to record levels. Despite increased calls from governments and the private sector to phase down or transition away from coal, it accounted for over one-third of total electricity generation.

In situ investigation of the excavation
01/09/2019This means that coal and rock is broken by excavation in two zones. The former zone has a distinct fractured interface, shown as the red line (Fig. 7 (b)), and the latter is the local fracture zone. Obviously, the extent of the ELZ ranges from 1.9 to 2.5 m in this investigation zone, but is nearly 4.5 m in the local fracture zone.

Breakage law and fractal characteristics of broken coal and rock
Broken coal and rock masses are the major part of the goaf. The compaction character- istics of coal and rock masses and the breakage law of whose particles during compac- tion exert an important influence on various aspects including control of strata motion, prediction of surface subsidence, and backfill mining.

Investigation of Seepage Law in Broken Coal and Rock Mass
Under this repeated loading and unloading action, the coal seam gradually changes from a complete state to a broken state. This process changes the pore struc- ture of the coal seam, and in consequence, the gas seepage law cannot be accurately determined. When the coal body is broken, the coal seam includes the broken coal particles.

Are coals oil
Fundamentally, oil expulsion from coals may only be possible where the following factors combine: an abundance of oil-prone kerogen (cuticle, resin, lignin, bacteria; Type D/E kerogen), mid-oil maturity (ca.0.8 – 1.0%Ro eq) and where expulsion efficiency is high enough to prevent oil retention and subsequent cracking.
