FINDING 1
There has been an incorrect terminology applied by both the Grosvenor Mine and the Mines Inspectorate since the first Methane Inrush in Development in 2016.
They have used the term “Floor Heave” and then regularly state as ‘being accompanied by’ or ‘associated with’ an uncontrolled methane “release”.
Methane is a “gas”.
RECOMMENDATION 1
The CMSHR 2001 Definition of “Inrush” in Schedule 9 be amended to
“inrush means an unplanned or uncontrolled flood “or release” of liquid, gas or material that has the potential to create a hazard.”
RECOMMENDATION 2
Creating a new specific “Methane Inrush Standard Operating Procedure” Regulation
