Embodiment Construction
[0026] The present invention will be further described below in conjunction with the accompanying drawings.
[0027] see figure 1 and figure 2 , the present invention provides a coal mine wide-grain grade intelligent dry separation process layout method, the transport roadway belt is divided into two sections, that is, the front section of the roadway belt 1 and the back section of the roadway belt 3, which are partially heightened at the reasonable position of the transportation roadway, Arrange primary grading roller sieve 2, the underground raw coal is fed to the primary grading roller sieve 2 feed port through the belt 1 head chute in the front section of the alley, and is graded by 50mm, and the -50mm under the sieve is fed to the outlet of the sieve under the sieve. Rear alley belt under roller screen 3. The lump coal on the sieve is sent to the lump coal belt 4 arranged in the local bottom breaking trough section through the outlet before the screen, and enters the i...

The invention discloses a layout method for a coal mine underground wide-grain-level intelligent dry separation process. The method is parallel to intelligent dry separation chamber developing in a main haulage roadway, relevant connecting roadways are developed, and the intelligent dry separation chamber is internally provided with a large coal intelligent dry separation system and an ultra-largecoal intelligent dry separation system. The method realizes +50mm wide-grain-level underground intelligent dry separation, has the advantages of being simple in process, low in investment, low in production cost, high in recovery rate, low in energy consumption, short in construction period and the like, studies organic fusion of many kinds of intelligent dry coal separation technologies to be applied to coal mine underground, the range of granularity processing is expanded, the processing quantity is increased, the actual coal mining capacity of a mine is improved, and the pressure of groundgangue treatment is reduced.
Description
technical field [0001] The invention belongs to the technical field of underground coal mine intelligent dry separation, and in particular relates to an underground coal mine wide particle size intelligent dry separation process layout method. Background technique [0002] There is a large amount of gangue mixed in the raw coal mined in coal mines. At present, most of the raw coal in coal mines is directly lifted into the shaft, and the coal and gangue are separated through the ground treatment system. threats and hazards. With the improvement of environmental protection awareness, the environmental standards and related requirements in the mining area development process are becoming increasingly strict, and the negative effects such as environmental pollution are becoming more and more difficult to accept, and even affect the survival of coal mines. Eliminating the hazards of gangue and comprehensive utilization of gangue have become arduous tasks for coal enterprises to ...
