Study On The Security Of Mined-ore Space And The Technique Of Mining Relicts In Tuancheng Iron Mine

Tuancheng Iron Mine is one of the old mines which is subjected to Administrating Bureau of Hanxing Metallurgical Mine. It is important to the sustainable development of Administrating Bureau of Hanxing Metallurgical Mine that it can continue producing. There are many mined-ore spaces in the authorized area because of the private mining which is devastating to the authorized mining. Otherwise, the resources remaining in the authorized area are not a lot. So, it is indispensible to mine the remaindering ore that the private mining deserted.The dissertationg is based on research of the spot. Then, the order of mining and the standard of the tunnels and the drawing-hole are fixed due to mensurating the parameters of the granular materials. The characters of the mined-ore space falling are got to the bottom of while the tracing obersavation and the measuring the bored hole are carried out in order to guide the efficient and safe production. All attain the non-falling accidence and the fruitful remaiding ore. Meanwhile, the research of the technique in picking messes is to be brought into effect. The results are applying in production of Tuancheng Iron Mine.
