- •
Prove the necessity of coal powders in outbursts, which normally exist in the structural areas underground.
- •
Take the outburst as a process of coal pneumatic conveying and obtain the different types of energy.
- •
Obtain the critical coal diameter to provide adequately fast desorption for conveying the outburst coal.
- •
Clarify the effect of rapid desorption on the outburst coal conveying. Summarize and deepen the outburst mechanism.
