1.1 Cardox. Developed over 60 years ago for use in explosive coal seams in the UK, the Cardox system consists of a high-strength, reusable steel tube filled with liquid carbon dioxide, a chemical energiser, and a rupture disc. When the Cardox tube is ignited, the carbon dioxide is almost instantaneously converted from a liquid to a gas.

Chemical weathering is the creation of sediment through chemical means. For example, acid rain can react with rocks, dissolving them. Erosion occurs when water transports sediment from one place to another. For example, a river can carry mud downstream. In general, water has more erosional power when it flows faster and has more volume.
blasting, process of reducing a solid body, such as rock, to fragments by using an explosive. Conventional blasting operations include (1) drilling holes, (2) placing a charge and detonator in each hole, (3) detonating the charge, and (4) clearing away the broken material. Upon detonation, the chemical energy in the explosive is liberated, and ...
