It is nessesary to resolve and study how to mine and utilize coal better. Now most countries in the world have taken an active part in research and development of new theory, new technology of coal mining and advanced mining machines manufacture, which can get the results of more safe and mor efficient coal mining and utilize it comprehensivly. The design bases on the condition of the mine called Jinggezhuang Coal Mining. All the desing resources are collected from the pit and the leaders′ introduction. After analyse the the original data, the author refers to many design manuals related and rules of law on mine. Furtheremore, the mining development system is designed which is the keystone and the difficulty. Comparing with some accessible projections, a shaft drinking system is found more suitable for the mine. Moreover, the transport system, the drainage system and the haulage system, etc, are all concerned in the design.
