Geophysical Studies for Prospecting Kerm Coal Deposit

For Prospecting of coal in Kerman deposit, many boreholes have been made in addition
to trenches and tunnels where well - logging operations have been done.
The purpose of these Well-Logging studies is to complete geological information to detmine lithological columns of drilling sections particulary coal seams to know the structure, thickness, depth, temperature as well as faulted zones and water leaking seams.
Geophysical studies as well as coal laboratory investigations in Kerman coal depostit have concluded the following facts:
1- There is close relation between ash content of coal, Gamma-Gamma Logs and GammaRay Logs.
2- There is close relation between parameters determining coal rank, technological properties of coal, Lateral Logs and Temperature Logs.
3- Physico-mechnical properties of covering and underlying rocks of coal seams show a close relation to Lateral and Gamma-Ray Logs.
Consequently by testing more than 2000 laboratory samples and studying Gamma-Gamma, Gamma-Ray, Lateral and Temperature Logs which have been done in about 150, 000 meters of drilling in Kerman Coal Deposit, various diagrams have been prepared which by the help of them
ash content, rank and technological properties of coal as well as physico- mechanical properties of adjacent rocks can be determined.
These diagrams contribute a great deal to explorating of coal deposits locating close to prospected areas.
