Factors affecting the layout of the middle section of transportation

The layout of the middle section of the transportation lane must first meet the requirements of the middle section production capacity (if there is a slippery well connected to the upper middle section to become the middle section of the combined Shimen, the transport capacity of the part of the ore from the upper middle section to the middle section should also be considered. There is room for transportation in the middle section to meet the changing needs of production, and at the same time, the production capacity of the ore block can be guaranteed.

For small and medium-sized mines, because the transportation capacity in the middle section is not large, it is generally used to transport the flat roadway with a single vein. If the transportation is tight, the width of the roadway can be increased at intervals of the transportation lane to make the local monorail widened. A two-track approach to improve the transport capacity of the middle section.

2. The thickness of the ore body and the stability of the ore surrounding rock

When the thickness of the ore body is less than 6~8m, it is usually arranged in a single vein roadway; the thickness of the ore body is above 8m, and a single vein roadway plus a vein roadway is used in small and medium-sized mines; only the extremely thick ore body is used. Roadway layout.

The middle section of the transportation lane is generally arranged outside the lower disc, and the stability of the surrounding rock of the lower section should also be considered. In practice, the middle section of the transportation lane is still less in the vein because the surrounding rock is not stable. It is because the middle section of the pulse long-distance transport can distribute the air volume to the coal blocks working at the same time, and it is not necessary to retain the pillars for protecting the transportation lanes.

3. Mining methods

If the mining method is the caving method (or other empty field mining method), the middle section of the transportation lane is generally arranged outside the vein, and is arranged outside the collapse boundary line of the lower middle section to ensure the return airway when the middle section is mined. In addition, the arrangement of the middle section of the transport lane along the strike or vertical direction of the ore body and its bottom structure can affect the location, number and loading mode of the loading point of the ore block.

4, ventilation system

The position of the middle section of the transport lane should have clear air intake and return air lines to minimize the turning. Avoid large corners and sharp corners (less than 90o) to reduce the ventilation resistance, and keep the middle section of the air duct for a certain period of time. .
