Embodiment Construction
[0010] The present invention will be further described below in conjunction with manganese ore mining by accompanying drawing.
[0011] see figure 1 , drive out the main mine road 8 along the bottom manganese groove, and open a winding mountain roadway 3 intersecting with the main mine roadway every 100 meters along the direction of the manganese groove 5. Rail transport vehicles 2 are installed on the main mine road and the winding mountain roadway. The slot 5 intersects and runs parallel to the main mine road with a circulation lane 9. Mining holes are excavated on both sides of the circulation lane to excavate manganese ore at intervals. A funnel 1 is set at the intersection of the roadway 3 and the circulation lane. Below the funnel is a transport vehicle, and the distance between the funnels is 20 meters The method of mining manganese ore into the circulation lane is: along the direction of the manganese groove, a rock ridge 6 is bidirectionally drilled a mining hole 7, a...
