A Shaft Excavation Construction Method for Multi-point Arrangement of Blind Shaft Sinking Facilities

Abstract

The invention relates to a shaft digging and laying construction method for arranging shaft sinking equipment for an internal shaft at multiple points. A mode of single horizontal arrangement in past shaft sinking measure engineering is changed; by fully utilizing existing engineering, a new thought of arranging the shaft sinking equipment for the internal shaft at multiple points within a range of vertical space is realized, and a signal of a shaft hanging scaffold, a signal of -600 m wellhead and operation equipment signals of -575 m gangue dumping platform and a -555 m mixing station and a -537 m winch are performed consistently and synchronously; and the shaft digging and laying construction method is feasible in theory and hoisting safety requirement.

Description

technical field [0001] The invention relates to a construction method for shaft excavation. Background technique [0002] In the construction of blind shaft engineering as the prior art, blind shaft sinking facilities generally adopt a single-level arrangement, and its main disadvantages are: first, the single-level arrangement in the underground is narrow and the drilling site is narrow, and there are great potential safety hazards; second, the single-level arrangement in the underground The layout requires more temporary sinking chambers, which has a serious destructive impact on the stability of the permanent system engineering; third, the excavation volume of the measure engineering is large, and the construction period is long, which increases the construction cost. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a shaft excavation construction method for multi-point arrangement of blind shaft sinking facili...
