Mechanism and Explosion-proof Design for a Coal

2011-1-1 · Introduction Coal is one fundamental energy source for human. However, coal mining is full of dangers. In the procedure of coal exploiting, lots of flammable gases, such as CH 4 , CO, etc, and coal dust are produced, which are easily ignited. In addition, coal itself is flammable too. There are many coal mine disasters all * Corresponding author.
