Generally Indian coals are low in TM (610 %) and the high moisture in Indian coals is due to physical addition of SM during the process or mining, transfer or handling. On the other hand imported coals contain high TM as high as 2540 % but most of it is in the form of IM and there is virtually no SM.
Moisture has been known to influence strata failures in coal mines for a long time. However, it is only in the last decade that researchers have attempted to quantify this effect. In the laboratory, attempts have been made to study the effects of moisture on the strength of coalbearing rocks, moisture gain in shales as a function of time and pressures generated due to swelling, slaking and swelling indices and their possible correlation to strata
