Problems solved by technology

[0002] If the medium-thick inclined broken ore body adopts the traditional mining method of sub-chamber and pillar filling, it is necessary to drive a connecting roadway from the sub-level entry to the mine room and the ore pillar. For the medium-thick ore body, the mining ratio will be lower. Relatively large, thus increasing mining costs

Embodiment Construction

[0023] Example Take the middle section of +750m~+700m of Maluping Mine of Guizhou Kailin Group Mining Corporation as an example.

[0024] The specific implementation steps are as follows:

[0025] 1. Divide the ore body into the middle section, the vertical height of the middle section is 50m, and the vertical height of the subsection is 10m; in the middle section, a spiral ramp is used to connect the subsection transportation roadways along the ore body, and the subsections are divided into ore houses and pillars without intervals , the width of mine pillars is 20m, the height is segmented vertical height of 10m, and the oblique length is 18.36m.

[0026] 2. Mining standard project: middle section transportation level roadway 1 → segmental level roadway outside the vein 2 → chute 3 → chute connection road 4 → mine exit road 5 → along the vein rock drilling roadway 6 → cutting up the mountain 7, arranged every 200m A mine shaft.

[0027] 3. Mining process:

Abstract

The invention discloses a diskless region type connection roadway continuous sectional cut-and-filling stoping method shared by a chamber and jambs for an inclined fractured ore body with medium thickness. The stoping method comprises the following steps that: the ore body comprises middle sections, wherein each middle section is internally connected with a fragmented transport roadway along the direction of the ore body by adopting a screw type ramp; the fragments separates the chamber and the jambs in a continuous way; and when the chamber is exploited, the connection roadway is advanced towards the centers of the jambs, the level of the ore drift is advanced along the hanging wall of the ore body till reaching the whole chamber, and the chamber and the jambs share one connection roadway; a filling retaining wall is constructed on the joint of the chamber and the jambs after recovery, the cemented filling is carried on a worked-out section from the upper subsection, in the middle sections, the chamber is recovered first and filled close the back, and then the jambs are recovered; after the jambs are recovered, a filling retaining wall is constructed in the connection roadway after recovery of the jambs, and non-cemented or cemented surfaces with thickness of 1m are used for filling; and continuous mining is realized through a plurality of technological parallel workings including drilling, blasting, supporting, ore removal, filling and the like in one subjection. The method provided by the invention has the remarkable characteristics of low accurate mining ratio, low ore loss factor, safety and efficiency, capacity of increasing enterprise revenues and the like.

Description

technical field [0001] The invention relates to a continuous subsection filling mining method for a panel-less ore-house-pillar-shared connecting roadway with a medium-thick inclined broken ore body. , Mining of medium-thick inclined broken ore bodies with low mining ratio and low ore loss rate. technical background [0002] If the medium-thick inclined broken ore body adopts the traditional mining method of sub-chamber and pillar filling, it is necessary to drive a connecting roadway from the sub-level entry to the mine room and the ore pillar. For the medium-thick ore body, the mining ratio will be lower. Relatively large, thereby increasing mining costs. Therefore, how to realize safe and efficient mining of medium-thick inclined broken ore body, low mining ratio and low ore loss rate mining is the innovation core of the present invention. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a low-mining ratio, s...
