GroundProbe’s Slope Stability Radar, supplied, installed & commissioned by Sujyoti at Sasti Opencast Mine of WCL Ballarpur has proved its utility within the first fortnight of its operation.

The Radar, which was commissioned on 6th October 2015, detected a wall failure on 16th October 2015. The Radar gave first alarm at 9.00 am on 16th October, showing the exact area of Dragline dump, where movement was recorded.

The Radar gave second alarm at 12.30 pm, when the Mine Management decided to withdraw men and machinery from the working coal-face.

At around 01.30 pm, the portion of the wall, detected by the Radar, collapsed resulting in sliding of material of 6000 m3 volume. An Hydraulic Excavator PC 650, which was deployed under the failed area, was removed before the actual failure. Thus, WCL could save the cost of its precious Mining Equipment and the lives of its two men, with the help of accurate & advance alarm given by the Radar. The mine produces 5000 T of coal every day.

The Radar software showed the movement in the wall as well as the photographic visual image of the area being scanned, which gave the exact location of the problem area, to take quick decision to evacuate.

Eastern Coalfields, where the latest accident has taken place, is a subsidiary of State-owned Coal India Ltd (CIL), the world’s largest coal miner.

Thursday night’s mine collapse at Eastern Coalfields Ltd’s Lal Matia coal mine in Jharkhand rounds up one of the deadliest years for those toiling deep in the bowels of the earth. The 17 mine worker deaths reported till January 1 sharply push up the mining fatality count for this year, which stood at 65 across both coal and non-coal mines during just the first six months of this year, for which latest data is available — translating into a fatality every three days.
