The detection of samples of a black rock-like substance, presumed to be coal deposits, by workers during a digging operation in connection with a drinking water project on the banks of the Godavari near Pamulapally in Ashwapuram mandal on Tuesday, has hogged the attention of officials of the exploration wing of the Singareni Collieries Company Limited (SCCL).

Acting on the reports, the officials concerned on Wednesday conducted a preliminary study about the substance.

GSI help sought

They, in turn, sought the help of Geological Survey of India (GSI) engineers, who are presently engaged in regional exploration activities to prove coal reserves in Manuguru mandal, to ascertain whether the substance is coal or not.

“As per the preliminary assessment, the substance appears to be black shale,” SCCL General Manager (exploration), Y.S. Babu Rao, said.

When contacted, he said, similar basement rocks resembling coal deposits were found during developmental activities by local people in the Yellendu area in the past. “We will determine the exact composition of the substance found at Pamulapally village on the basis of the toposheet,” he said.

“Some technicians of the GSI are expected to visit the site at Pamulapally on Thursday,” said Venkataramaiah, the project officer, Opencast Project, Manuguru.

They will determine the characteristics of the substance that was found during the digging operation, he said adding that the material resembled black shale.
