HARGREAVES Services will today issue workers at an at-risk colliery

with notification of potential redundancies.

Maltby Colliery, in Rotherham, South Yorkshire has been producing coal for more than 100 years, but the presence of gas, water and oil in the development of a new face has fuelled uncertainty over the site which employs about 500 workers.

Esh Winning, County Durham-based Hargreaves is awaiting reports later this month that will advise on the geological, financial and health and safety risks associated with the pit.

A statement said: "The Company will shortly begin consultation regarding potential redundancies. This consultation process will last for a minimum of 90 days. Initiating this process is considered to be prudent business practice and does not indicate that a decision on the future of Maltby has been taken."
