Embodiment Construction

[0017] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0018] Depend on figure 1 , figure 2 As shown, the Ⅱ# ore body of an iron mine has a dip angle of 20°-60°, a thickness of 5-15 meters, and is distributed in a layered and stable manner, with a strike length of 1200m. The ore bodies within the scope belong to the type of iron ore deposits that are difficult to mine, and the surface of the iron ore deposits cannot be deformed and collapsed. According to the occurrence conditions of Ⅱ# ore body, combined with the preliminary mining design of the iron ore, a segmented open-field mining chassis of the present invention is selected to be used in the section north of the Ⅱ-1 exploration line in the middle section of -380m and the middle section of -320m. The filling mining method specifically includes the following steps:

[0019] Step A, ore block structure division: the ore block is arranged along the ore body...

Abstract

The invention provides a sublevel opening stoping mining chassis route ore drawing subsequent filling mining method. The method specifically comprises the steps of conducting ore block structure dividing, stope preparation, cutting, stoping and ore removal operation and filling; and the step of conducting the above steps circularly until stope mining is completed. According to the method, compared with a traditional sublevel open stoping mining method, separated mining and separation of ores and rocks are facilitated, horse stone in ores can be effectively screened out, the dilution ratio of the ores can be greatly lowered, the quality of supplied ores is guaranteed, and the problem of difficult application and popularization caused by dilution and high loss rate in the process of slowly inclined ore body stoping existing in the traditional method is solved. Meanwhile, according to the method, during stoping, top and bottom pillars do not need to be reserved, and stoping barrier pillars also do not need to be reserved. Compared with the traditional method, the recovery rate of ores is high, stope preparation work amount is saved, and the cost is lowered.

Description

technical field [0001] The invention belongs to the technical field of mining methods, and in particular relates to a segmented open-ground mining chassis approach ore-drawing followed by filling mining method. Background technique [0002] The mining method of subsection emptying and subsequent filling is to divide the ore block into several subsections in the vertical direction; the mine room and ore pillar are arranged on the level of each subsection, and the ore mined in each subsection is separated from each subsection respectively. After the sub-section mining is completed, the ore pillar of this sub-section can be mined immediately and the goaf can be filled and processed at the same time. In recent years, with the popularization and application of trackless equipment in our country, the mining method of subsection empty field and subsequent filling has been vigorously developed. However, the traditional segmented empty stop and then filling mining method is only sui...
