ABSTRACT:
The invention provides methods and apparatus useful primarily in the presplitting and blast removal of earth formations, the improvements according to the invention involving the use of inflatable devices suspended in boreholes used in shattering earth formations. The inflatable devices of the invention can be of various shapes and are provided with valves to allow a fluid such as air to be pumped into each device on placement of the device at a desired location in a borehole. The inflatable devices are preferably formed of a flexible, polymeric material which allows a desired degree of stretching to cause plugging of a borehole. The "plug" formed by an inflatable device of the invention allows loading of explosives into a borehole in order to produce desired blast results according to the several methods of the invention.
