Embodiment Construction

[0044] The present invention will be described in further detail below in combination with 21 drawings and embodiments.

[0045] attached figure 1: Schematic diagram of the mechanical equipment and construction method for mud backfilling in the goaf of the mine. The speed-regulating hoist (1) is placed on the top of the cliff side of the excavation surface (2) of the loess mountain body. The hoisting wire rope (3) is wound on the drum of the speed-regulating hoist (1), and its end is hung with a double-shaft reciprocal (clockwise and counterclockwise) three-way (radial, end-to, oblique) rotation Mowers (4). The two-axis reciprocal (rotating clockwise and counterclockwise) three-way (radial, end-oriented, and oblique) rotary soil cutter (4) is close to the excavation surface (2) of the loess mountain to perform up-and-down reciprocating cutting motion. The loose soil material (5) that has been cut and stripped from the mountain body falls and accumulates on the soil field at...

Abstract

The invention relates to mining area ground subsidence prevention and in particular relates to mechanical equipment and method for backfilling slurry in a mined-out area. By the use of the machinery equipment, the operation method and a tunnel plan, a coordinated process of soil exploitation, water distribution and filling mined-out area targeted work including vertical mechanical soil fetching on the loess plateau, soil up-well and down-well transportation via an aqueduct can be achieved. The mechanical equipment and method for backfilling slurry in the mined-out area are suitable for subsidence prevention engineering work of deserts and the loess plateau and mined-out areas with water sources. The development and application of the mechanical equipment and method play an important role in eliminating mine roof gas water inrush accidents, mountainous flood peak rear-end superposition, breakage of worldwide difficulties of earth dam construction subsidence cracks, effective control and management of mountainous water and soil resources, establishment of dotted artificial lakes and trench platform mechanical farms, improvement of conditions of local natural environment ecological vegetation temperature and rainfall.

Description

technical field [0001] The mechanical equipment and method for mud backfilling in goafs of mines according to the present invention belong to the backfilling technology for the prevention and control of goaf subsidence in mines (such as coal mines, iron ores, aluminum ores, etc.) mining methods (such as water-sand filling mining, paste filling mining) field. Background technique [0002] The reason and path of filling mining. After the mining of mineral deposits, geological disasters such as land cracks, surface spring water cut-offs, house collapses, and landslides occurred successively on the ground above the goaf. It has caused conflicts between villages and mines, and led to many social and economic problems such as resettlement and relocation, restoration and governance. Filling mining is to use foreign materials such as gangue, sand, gravel, fly ash and other materials to fill the goaf, so as to control the movement of rock strata and ground subsidence.
