Embodiment Construction

[0024] The technical scheme of the mechanized segmental filling mining method of vertical hole and horizontal hole cooperative mining provided by the present invention is as follows:

[0025] ⑴. Divide the ore body into the middle section along the height direction, and then divide the middle section into subsections, arrange the ore body along the trend or vertical direction, and determine the reasonable length and width of the mine room according to the stability of the ore rock, as a recovery unit;

[0026] (2) Segmented roadways are arranged parallel to the boundary of the ore body, and each segmented roadway is connected through the segmented connecting roadway and the inclined roadway, the stope is connected with the segmented roadway through the stope connecting roadway, and the stage transportation horizontal roadway passes through the chute and the segmented horizontal roadway China Unicom, thus forming a non-pulse trackless mining quasi-system;

[0027] ⑶. Excavate ...

Abstract

The invention discloses a mechanical sublevel filling mining method adopting vertical hole and horizontal hole cooperative recovery. According to mine sublevel recovery, vertical hole recovery and horizontal hole recovery are cooperatively performed in a sublevel recovery unit; a vertical hole comprises a pre-splitting hole and an ore breaking hole, most of the ore in the unit is recovered in the vertical ore breaking hole, a unit ejector plate is formed by horizontal hole recovery, two outlines of the unit are controlled by the vertical pre-splitting hole, the ore is discharged cooperatively by a common scraper and a remote control scraper after recovery canopy guard, a unit goaf is filled at a time, and a drilling space is reserved for the upper recovery next sublevel. The operation is cycled until the whole one-step stope recovery is finished. The characteristics of high strength, high efficiency and low cost of sublevel recovery are exerted, the two outlines of the sublevel recovery unit are controlled by utilizing pre-splitting blasting, and the outline of a recovery unit ejector plate is controlled through the horizontal hole recovery. The method has the advantages of safety, high efficiency, simple process, low loss and dilution and high mechanical degree.

Description

technical field [0001] The present invention relates to a mining method, in particular to a mechanized segmental filling mining method in which vertical holes and horizontal holes are used for synergistic mining, which is suitable for ore rocks that are more than moderately stable, inclined or gently inclined thick and large ore bodies, and steeply inclined medium-thick mines. safe and efficient mining. Background technique [0002] With the continuous improvement and development of mining technology and mechanical equipment, the shortcomings of the layered filling method, such as low production efficiency, high mining costs, and high two-rate indicators, are gradually exposed when mining thick and large ore bodies. The filling method has gradually evolved into the segmented filling method and Stage filling method, and stage filling method has stricter requirements on ore body occurrence conditions, so segmental filling method is more adopted by mines. [0003] For the prob...
