ABSTRACT:
The present invention is directed to a cartridge for use in fracturing materials, such as rock. The cartridge includes a base member, a body member, a propellant, and a device for sealing a surface of the cartridge to the surface of a hole in the material. Upon ignition of the propellant, gas pressure rapidly rises in the hole due to the sealing device. The gas pressure causes the material to form a penetrating cone fracture. Various cartridge configurations are presented depending upon the specific needs of each application.
