The strength and structure of filled body, access compact rate or admission rate affected and decided directly the mining safety degree and filling cost of access back-filling method. In this paper, it is discussed that how to determine the filled body strength and structure of access back-filling method, and how to improve filling technology to raise the access compact rate or admission rate.
By analyzing the importance of mining safety laws,policies,technologies and management,this article expounds the significance of building up a safety cultural system which is made up of laws and statute,system of policy,technologies and management.
It is important to investigate the deep reasons of the mining safety in production. To realize this target,we should start from the administrative morality perspective and combine the speciality of the mineral industry administrative management with it.
Referring to the phenomena of the administration morality,we can then thoroughly investigate the reasons,form a system in the administrative area,such as administration structure,the superintendent structure and the protection of the miner's rights and benefits,etc. We can also hold back the various problems of the mineral industry production effectively,and ensure that the management of mining safety proceeds efficiently,safely and uniformly.
