Embodiment Construction

[0030] The following will support and further explain the present invention in conjunction with specific embodiments and accompanying drawings, but the following descriptions do not constitute limitations on the claims of the present invention.

[0031] There is a sharply inclined broken ore body with a strike length of 500m on the two wings of a Shaba mine, and a thickness of 4-8m, which belongs to the medium-thick ore body. Due to the fragmentation of the ore body, the safety of mining is poor. For this reason, an artificial false roof protection mechanism is constructed, and the ore body is mined downward and high in sections under the roof protection. Adopt method of the present invention to construct artificial false roof below.

[0032] ①Use the 1100 segmental rock drilling roadway in S4 panel area S3# of Shaba Mine to have an average width of 4m and a length of 18m. Structural construction and construction to protect the workers in the lower section to return to the mi...

Abstract

The invention discloses a quick and low-cost artificial fake roof construction method for a ground mine. Under an extreme smashing and exploring condition of ore rocks, an artificial fake roof is pre-constructed to form a safe protection layer by using a downward cemented filling mining method; according to an actual situation of the mine, under the combination of a cable-stayed bearing theory, a plate block theory and the like, a high-intensity plate block structure integrated with an anchor rope, an anchor rod and steel bar concrete is obtained; a safe and economical artificial fake roof structure is supplied to subsequent mining. Compared with the conventional artificial fake roof construction method, the quick and low-cost artificial fake roof construction method disclosed by the invention has the outstanding advantages of science, rationality, high bearing capacity, low construction cost, safety and reliability in use, quick construction technology, high efficiency and the like.

Description

technical field [0001] The invention belongs to the technical field of mining, and relates to a fast and low-cost method for constructing artificial false roofs in ground mining mines. The protective structure realizes the safe and efficient mining of the ore body. technical background [0002] In underground mine engineering, the artificial false roof is an artificial roof protective structure constructed of engineering composite materials, which is used to bear the load of the upper broken ore rock or filling body, so as to ensure the safety of the workers under the artificial false roof. In the mining process of ore-rock broken ore bodies using methods such as artificial environment reconstruction method, downward segmental filling method and caving method, it is necessary to construct an artificial false roof protective structure. In the construction methods of artificial false roofs at home and abroad, similar projects or experience are often used for construction. Due...
