The co-combustion of sludge and coal in the existing coal-fired power plant is a promising way for the disposal of sludge. However, slagging in boilers is one of the potential problems if the sludge was mixed improperly with coal during co-combustion.

When it comes to mining coal, there are two processes by which coal can be removed from the ground: surface mining, or underground mining. In Australia, the majority of coal mining is done via the opencast method, although often the method of choice is dependent on certain characteristics of the coal deposit 1.. The opencast, also referred to as the open-pit method, is the ideal technique when
