broken coal into shuttle cars for delivery to a conveyor, and then bolting the mine roof in the excavated area. To provide a steady flow of coal in a roomandpillar mine, several stages of mining occur simultaneously in different rooms. A final phase of mining termed "retreat mining" may be performed to recover additional coal by
These different type briquetters works under different pressures. As a matter of reducing the pressure for briquette making, binder thus plays an important role. Using binder will make some kinds of materials work with different types of briquetter due to the lower pressure requirement. Binder also gives a high strength to the briquette.
