A new method for the rational arrangement of gas drainage boreholes
The effective radius and the rational distances between boreholes for gas drainage in coal seams are two of the fundamental parameters for the rational arrangement of boreholes in a gas drainage system. Mathematical formulae for the rational arrangement of boreholes for gas drainage in coal seams have been deduced based on the theoretical model of coal gas dynamics. It is shown, by using the formulae for calculations for actual areas in the collieries, that these formulae, which have primarily been applied in the design of a gas drainage system for the prevention of coal gas outbursts, are rapid, simple and useful.
