Kunming Iron and Steel of mine construction conditions

The amount of raw materials. Dahongshan by the different size of iron ore mining to meet the Kunming Iron and Steel 200 million t of steel for the mining program as shown in Table 6. Table 6 through the analysis of some key indicators, Kunming Iron and Steel is easy to see effects of the recent mine construction or better, can be grouped into the following aspects. 4,1 to Kunming Iron and Steel developed to target 200 million t of steel, iron ore supply regardless of which program is feasible and there is a certain economic and social benefits, and have left some room. 4,2 Dahongshan Iron should seize the building, if the introduction of foreign trade, can take large-scale development programs, such as insufficient funds park can also be taken to advance the upper part of open pit mining of iron lava guitar program, Table 6, the main indicators for the mining program 46 shy Wrap Design and construction of mine No. 2 of 1996 re-development of the shallow pit iron ore opportunistic, and eventually the construction of iron ore mining exploration Department of steps. 4.3 regardless of the program for the mining, new mines for thirty points must be put into the building, it is because: After the completion of thirty points of new mines. 5O million t per year to provide about finished mine, if for the acquisition of mineral deposits, then have to spend billions of money every year, but is difficult to guarantee the quality and quantity of ore. Construction of three new mines into account the investment point of about 1 billion investment in Queensland after the steel can be owned for as mine base. b. Alternative. Forty old mine production capacity, while addressing the placement of existing staff and equipment c. Before 2060 can ease the construction period Dahongshan Iron not supply and demand of the time scale spears lip, to Kunming Iron and Steel to provide ore raw materials. d. Dian beach is high-quality magnetite (rich block, powder ore). Fu Ning gold is easy to choose peace and magnetite, are good open pit mining conditions. Inadequacies of the transport distance, but lower than the acquisition of other mine sites in the province is still better conditions. Put into the building should not be affected. e. Thirty new mine sites Kunming Iron and Steel to go local government welcomes the development, in co-operation can take a variety of mining mode of operation during the period, 'the new mines can enhance business and social benefits. 4.4 The acquisition and use of small ore occurrences imported ore to Queensland. Watch actinium geographical location, should only be regarded as a supplement. Integrated above. Kunming Steel's iron ore needed for development, as long as there is a certain investment is fully guaranteed, and the current production indicators have improved and enhanced. At the same time will bring certain economic benefits and room for development, the yield of 13 or more types of mines and domestic rhino is relatively favorable conditions for mining. Contributions Date 1995-1o-22 About Chenqi Zhang. Metallurgical Design and Research Institute long copy chief architect engineer. (Continued from page 15) the mining process is usually used to. Set in an integrated graphical environment dynamic capture switch method can solve this problem. The body of practice is the command line into P0LY (polygons) command, when you need to draw the public side, open the nearest point of capture switch, then the nearest point of the graphics cursor is captured by l state, move the cursor to the edge of the public, press the left mouse button or keyboard INS key, the system searches the memory cable around the polygon. And capture the coordinates of the points to take the cursor to the current point, and so the edge of walking in public, captured a series of public polygon points, while leaving the public side. Press CTRL + B key (to cancel or load) the nearest point of capture mode, the cursor back to normal, continue to draw other polygon point to completion. 8 Mining Sites of similar paint 8.1 mapping of the common side of the polygon method, P (} LY (polygons) command or PLINE (multiple connections) commands, polygon mining along the boundary line B to go, thus forming a mining Li-like field lines, because the status quo line is the simulation of the actual boundary line mining production, so there is no error. 8.2 with CONT (contour tracking) command. automatically track the status line of the final stope. At this point the state to be mined file, because the contour is based on the steps of unit blocks the formation number. As Simulating terrain model in the initial mining on the beginning of the current state is given by modifying the file dynamic terrain obstacle, the difficulties of this, with the tracking contour The method can solve both the synthesis problem. Of course, as with the traditional method to track the status of the contour lines obtained with the actual formation of the polygon boundary line between the exploitation of the error still exists. If you see a deviation in the ring too can be used as solutions. ugly 'when the polygon after mining, with the CONT command to trace the contour, b. the polygon closest to the exploitation of the contour cross delete} c-polygon based on the common method of drawing, using equivalent contour line and polygon drawing near the new mining d. Select the polygon polygon, the first filling, and then mining. This state of access to the actual exploitation of the contour lines were completely consistent. Received ugly period: 1995 ・ II a 13 About the t pay attention Jianhong, Central South University of Resources and Environment and Civil Engineering. Associate Professor, Master.
