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...

Abstract

The present invention provides a mining method of mono-layer or multi- layer compartment metal mine, which includes the following steps: first build a main mine path 8 along the metal mine strip on the bottom layer; then build a drive spiral road 3 in every 80-120 m that intersectant with the main mine path along the direction of the metal mine groove, a cycle traffic lane 9 that intersectant with the metal mine groove 5, a funnel 1 is provided on the interface where the spiral road 3 and traffic lane 9 meets; dig mining hole 7 in interval to fetch metallic mineral in grooves on both sides by taking rock ridge 6 as support along the direction of metal mine groove after entered into the cycle traffic lane; dig onwards along with the mining holes in echelon, and the cycle traffic lane and the spiral road deepens together. The present invention reduces digging on useless rock ridge when mining, and replaces original upright post support with rock ridge supporting effect, can effectively prevent mining mountain massif from subsidise and fracture, particularly security problems like collapse or subsidence of neighboring industrial area and residential area; waste ore backfilling saves a great amount of labor and material consumption, and extraction efficiency is 2-3 times of that of original extraction.

Description

technical field [0001] The invention relates to a method for continuous mining, backfilling and transportation of underground mines, in particular to a method for mining metal ores such as manganese ore with different thicknesses of rock ridges and metal ore layers. Background technique [0002] The old-fashioned mining is under the bottom metal mine such as the manganese ore layer. Firstly, the main mining road is opened, and a winding roadway is opened every 60 meters. At the winding mountain roadway, a patio is opened upward to the manganese ore layer every 20 meters. It is used during mining. The mining face with a height of 1.6 meters and a width of 60 meters is pushed forward in parallel, which is a clear mining method, so there are many waste ores and a large amount of outbound transportation. In addition, the middle circulation lane is 3 meters wide, the lane is paved with rails, and a large-diameter pillar is erected every meter on both sides of the lane, and the st...
