Embodiment Construction

[0018] Embodiments of the present invention are further described below in conjunction with accompanying drawings:

[0019] In this embodiment, the thickness of the ore body is large, and the thickness of No. 37 survey line is 65 meters; the dip angle of the ore body of No. 38 survey line is 67 degrees, and the thickness is 67 meters; The ore body is 59 degrees, and the thickness is 56 meters; the overall dip angle is between 45-60 degrees, and the thickness is 55-75 meters. The design adopts the mining method of segmental emptying and subsequent filling, rock drilling in segments, and ore extraction in stages. The specific implementation method and steps are as follows:

[0020] 1. Block layout (such as figure 1 , 2 shown) and structure parameters:

[0021] The ore blocks are arranged vertically, the width of the ore block is 30m, and the length is the thickness of the ore body. A total of 17 ore blocks are designed in this area. Each ore block is divided into two mining...

Abstract

The invention relates to a sublevel open subsequent filling stoping method, belongs to the field of mining engineering and is particularly applicable to ore bodies with large and continuous dip anglesand larger thickness. An optimization technology of the sublevel open subsequent filling stoping method is provided, the problem that mining engineering construction is operated in spaces with largeropen roof areas is solved, mining operators can always perform construction in roadways instead of entering large gobs for operation by changing a traditional mining method, so that a better construction operation environment is created, and the production cost is reduced.

Description

technical field [0001] The invention relates to a segmented open field followed by filling mining method, which belongs to the field of mining engineering and is especially suitable for ore bodies with large inclination angles, continuity and large thickness. Background technique [0002] With the rapid development of modern industry, the demand for ore continues to increase, the mining depth gradually increases, the weight of mining operations becomes more and more heavy, and there are more and more types of mining methods. However, when traditional mining methods are used to mine large, continuous, and thick ore bodies, mining operators usually have to enter large goafs, which poses a greater safety hazard. Contents of the invention [0003] The technical problem to be solved by the present invention is: to overcome the deficiencies in the prior art, and to provide a segmented open field and subsequent filling mining method, so that the mining workers are always working ...
