Embodiment

[0029] see figure 1 , in the gob shown in the illustration, the filling method of using fiber braided net to strengthen the solidification of tailings is a specific embodiment of the present invention. In the goaf, tailings are used for filling, and several layers of fiber braiding are embedded inside the formed filling body. The fiber woven net is woven into a net through fiber monofilament 2. In this embodiment, the fiber woven net is cross-formed by several transverse fibers 21 and some longitudinal fibers 22, and the transverse fibers 21 and longitudinal fibers 22 of the fiber woven net boundary are The ends are respectively fixed on the surrounding rock walls of the goaf, and the transverse fibers 21 and longitudinal fibers 22 are used as fiber monofilaments of the fiber woven net, which are fixed by hooks 3 anchored on the surrounding rock walls of the goaf, and filled in the gaps of the fiber woven net. The tailings filling solidifies to form a filling body.

Abstract

The invention discloses a fiber braided net reinforced tailings solidified filling structure and its filling process. The filling body contains several layers of fiber braided nets. The grid gap filling tailings filling is solidified to form a filling body. In the field of mine filling technology, the invention innovatively uses composite fiber reinforced materials with high tensile strength to connect into a network to lay gobs, thereby enhancing the mechanical properties of the tailings filling body. The construction is convenient and convenient during the application process, and can effectively reduce cement, etc. The loss of cementitious material can significantly reduce the comprehensive filling cost while increasing the curing strength. It is especially suitable for the approach type and upward layered stope filling with a small stope exposure height. It is a kind of good economic benefit and limited The tailings filling scheme with few conditions improves the overall performance of the tailings filling body in the goaf of the mine, and has good economic benefits and promotion value.

Description

technical field [0001] The invention belongs to mine filling technology, in particular to a fiber woven net reinforced tailing sand solidification filling structure and a filling process thereof. Background technique [0002] In modern society, mineral resources are an indispensable material basis for human survival and development. In the process of rapid economic development, more than 95% of China's power and 85% of industrial raw materials are derived from mineral resources, but mineral resources It is a non-renewable natural resource. In order to improve the utilization rate of mineral resources and increase the service life of mineral resources, it is becoming more and more important to maintain and develop green and sustainable mines. Especially since the 21st century, the pollution and damage to the environment caused by industrial civilization has caused the Therefore, the development of the mining industry has also entered a new stage - green mines. The full tail...
