Shallow-hole rock drilling blasting force-electric harrow cooperated carrying segmented ore chamber mining method

Abstract

The invention provides a shallow-hole rock drilling blasting force-electric harrow cooperated carrying segmented ore chamber mining method, which comprises the following steps of dividing a multi-layer inclined thin ore body into different stages; in the stages, dividing each ore layer into ore blocks along the trends; dividing an ore chamber and an ore post in each ore block; dividing segments for the ore blocks; arranging an along-vein stage conveying roadway in an ore vein, wherein vein passing conveying roadway digging is needed when the ore layer is more than two layers; in the stages, sequentially performing lead mining in each ore layer from top to bottom; using shallow-hole rock drilling in the ore blocks; using blasting kinetic energy so that ores slide and fall to a segmented bottom plate; harrowing the ores into a drop shaft by an electric harrow arranged at the segmented bottom; sliding the ores to the stage conveying level; conveying and lifting the ores so that the ores are finally conveyed to the ground surface. The method has the advantages that a shallow-hole blasting force carrying technology is applied to the multi-stage inclined thin ore body mining; the out-of-vein work amount is reduced; the production capability and the carrying efficiency are improved.

Description

technical field [0001] The invention relates to a mining method for underground mining of metal mines, in particular to a shallow-hole rock drilling blasting force-electric rake cooperative transportation segmented mine room mining method, which is suitable for uniform stability of hanging wall rocks, interlayers and ores. It is a multi-layer inclined thin ore body above medium level. Background technique [0002] The mining of inclined thin ore bodies is limited by the occurrence of ore bodies. Generally, it is not suitable to use large-scale equipment and medium and deep hole blasting. Instead, the comprehensive mining method of retaining ore, and the traditional explosive force transportation mining method that is segmented along the trend or inclination of the ore body are mostly used. For the mining of single-layer inclined thin ore bodies, the above-mentioned mining method has certain advantages, but when it is used for mining multi-layer inclined ore bodies, the produ...
