Vertical deep hole falling mine sublevel caving mining method typical plan - mining work
It is the layout of the next off-board. That is, ore transportation, pedestrian, ventilation, materials and other mining projects are arranged outside the lower disk. The stage transportation is a circular transportation system for the pulsed loading.
Because if these roadways are opened in the veins, the main transport lanes will be destroyed along with the mining blocks, so that the wind flow is not guaranteed.
(2) Sliding well layout: The upper two sections adopt inclined inclined chutes. The next two sections use independent vertical mines.
(3) Electric roadway: The electric raft of this method is also arranged outside the lower disk, using a single-side sulcus funnel.
(4) Pedestrian Ventilation Patio: It is not provided for each of the ore blocks, but a ventilated pedestrian well is provided for every 2 to 3 ore blocks, and is connected with the sub-sections of the electric roads for pedestrians and air intake. The patio of the material is used, and pipelines are laid in the patio. (generally one set per mining area)
(5) The high-slip well of each ore block: the high-slip well of each ore block is connected with the extra-vehicle transport roadway of the upper stage, and communicates with each section of the electric roadway by the contact road as the back of each section of the electric ramp. Wind patio. (The figure is not connected, it is actually connectable. It can also be disconnected)
