Problems solved by technology

Due to the limited space for underground work and inconvenient material transportation, the current artificial pillar construction process has disadvantages such as complex construction process, high labor intensity, low production efficiency, large cement consumption and high production cost, which is not conducive to mine cost reduction and efficiency increase, and is difficult to meet the requirements of high efficiency. Mining requirements restrict the sustainable development of mines

Abstract

The invention relates to a civil engineering mold bag which comprises a mold bag body (2). At least one opening is formed in the mold bag body (2), and a feeding pipe (4) is arranged at the other end of the mold bag body (2); and the exterior of the mold bag body (2) is sleeved with supporting rings (3) matched with the mold bag body (2) every 50-250 mm, and the supporting rings (3) are fixed to the corresponding positions of the mold bag body (2) through at least one bag loop (6). According to the civil engineering mold bag, the civil engineering mold bag sleeved with the reinforcing supporting rings is used as a soft mold to construct a down hole artificial pillar, a pillar body is formed by grouting at a time, construction is easy and convenient, and the speed is high; the constructed artificial pillar is high in integrality and good in stability; and according to a method for quickly constructing the artificial pillar, the down hole mold erecting working procedure is simplified, the constructing efficiency is improved, transporting is convenient, construction is easy and rapid, and the method is particularly suitable for construction of projects such as mine pillar body underground mining.

Description

technical field [0001] The invention relates to a geotechnical mold bag and a method for quickly constructing an artificial pillar, belonging to the field of mining engineering. Background technique [0002] When mining horizontal or gently inclined ore bodies, in order to ensure the safety of stope mining and the stability of the roof, various forms of ore pillars are generally reserved. These reserved ore pillars account for about 25% to 30% of the stope ore volume, resulting A lot of waste of resources. In order to improve the resource recovery rate of mines, prolong the service life of mines, ensure the safety of mining and realize the comprehensive recovery and utilization of mineral resources (residual ore recovery), it is an effective method to replace high-grade ore pillars with artificial pillars. [0003] The artificial ore pillars used underground are generally (reinforced) concrete columns. The construction method first needs to support the formwork (or external...
