Based on the condition of supersaturated overburden in Dunliu Colliery, using the methods of alternation excavation and temporary support with fabricated bar reinforced piles, the main vertical shaft was rapidly constructed with high quality through the supersaturated overburden.

Aiming at the problems that the interval number of network interface to open is too much and the network selection time is too long in dynamic activating interval algorithm, a network interface activating interval algorithm based on terminal battery state is proposed, which makes the terminal remaining battery state β as weight of power consumption cost.
