Mining Zone

The mining area belongs to the case of the monoclinic structure. the monoclinic structure is composed of the Strata and Carboniferous strata. the mining zone exists in the contact zone, the Central Ordovician Majiagou group composites the ore body, the rock and the contact zone is basically same, surrounding rock with the contact zone is bending and bending, individual lots miter Wai now edge, the contact zone, and fracture of composite ore-controlling. The output form of the ore body is usually a short distance within the surrounding rock was synchronized fold in the form of a supine step, sawtooth or anticline. Faults can be divided into two groups according to ie, NNE-NE, NW NNW direction two groups, mostly normal fault mineralization after breaking away from the little that the body integrity.

The magmatic rocks within the mining area hot mountain is diorite pyroxene biotite, diopside Petrochemical the diorite dykes of quartz monzonite, diorite porphyry and lamprophyre and diorite. The diorite is the footwall of the orebody. From the horizontal or vertical, wall rock alteration from long distance to near the ore body in turn is a large group of rocks, no alteration or minor alteration of the surrounding rock formed by thermal alteration crystalline limestone magnetite body contact metasomatic mafic the formation of a variety of skarn magnetite body rock door mafic of alkali metasomatites the normal composition of magmatic rocks. Hydrothermal alteration for added to the above rock wall rock alteration. During the beneficiation of such ore to pay attention to the magnetic separator in mineral processing equipment and the choice of the flotation machine.

Magnetite, the main ore body is about 2000m, from east to west, the change trend is from NNE to NE, tendency by SEE gradient it and dip is 400 to 900, mainly steeply inclined along the tendency to intermittent extension is 500 600 m. The average thickness is about 12 m, the eastern ore body is thick, complex form, which was now edge of the veinlenticular, lenticular, often branching and serrated western occurrence is more stable press-like ore body. The ore minerals were relatively simple, in which metallic minerals are magnetite, followed by mainly pyrite, chalcopyrite, bornite, chalcocite, digenite, hematite. A small amount of copper, malachite and pyrrhotite and network trace amounts of sulfur and copper and cobalt mine, the door and then copper, the door and then gold. Gangue minerals as serpentine, calcite; followed by the mica, chlorite, and small amounts of diopside, tremolite, etc.. Ore structure to its shaped grain-like structure is well developed, followed is the door-shaped half-shaped granular structure giving an account of the residual structure and fragmentation of the structure.

Workshop Decoration

You've been intends to buy Overlock, picking up and finally made the decision. New Overlock ready to decorate the interior of your workshop. But before you immerse yourself in learning the subtleties of your new other, it is best to read the instruction manual of the equipment. After spending some time on this procedure, you will be able to prevent future problems with my overlock. What to do: Always use four identical threads to work on the overlock.

Do not be afraid to use as many threads. Remember that usually spends looper about five meters of thread. This will help you to include in the process all spool simultaneously. If you do not want to use a lot of threads, then you should buy the small spools. Note, however, that the lifetime warranty of any kind of thread does not exceed five years. Do not forget this. You should use nitederzhatel for easy sewing.

If you offer a complete training courses on work overlock, do not give up. Maybe you know how to sew and have used overlock, but should Considering the fact that the new acquisition may not perform the functions familiar to you. It is necessary to study in detail the operating instructions, since warranty does not cover damage caused by inadvertence, admitted inexperienced seamstress. Time to change your needles properly selecting the size you want. Malfunction overlock arise primarily from the use of wrong size needle. It should be noted that needle overlock to change at the same time, even if broken, only one of them. Do not forget to invite the master 1-2 times a year and regularly check overlock. This procedure is very important because it can prevent serious problems. Don'ts: Do not throw away the carton and packing material, since it can be useful for transporting overlock. Step by step refill thread in overlock. In no case do not violate sequence, as this can cause unforeseen problems. Do not panic if there are problems in the overlock. Check that you have prepared him for the top job. You may be missing something. AND yet. Rejoice in the unforgettable opening hours to overlock. Overlock can save a lot of time and create a work of art.
