Abstract

The invention discloses a comprehensive survey method for a large-span shallow-buried limestone goaf, and relates to the technical field of underground mining. The method comprises the following stepsof data acquisition, geological investigation and mapping at the survey area, special investigation of the survey area, and geophysical prospecting, engineering drilling, geomechanical simulation test, establishment of a geological survey BIM model, preparation of survey results report and data collation and archiving in goaf. The comprehensive survey method provided by the invention has the beneficial effects of solving the problem of low survey accuracy of the large-span shallow-buried limestone in urban dense areas, having safe and reliable operation, and providing relatively accurate first-hand information for the suitability evaluation of the design and management of similar projects, land use and urban underground space utilization.

Description

technical field [0001] The invention relates to the technical field of underground mining, and more specifically, the invention relates to a comprehensive survey method for large-span shallow buried limestone goafs. Background technique [0002] The goaf is a "hole" created by man-made excavation or natural geological movement below the surface. The existence of the goaf makes safe production face a great safety problem. Personnel and mechanical equipment may fall into the goaf and be injured. [0003] Since the underground goaf has the characteristics of strong concealment, poor regularity of spatial distribution characteristics, and difficulty in predicting the roof collapse and collapse of the goaf, how to determine the distribution range, spatial shape characteristics and characteristics of the goaf Quantitative evaluation of caving conditions has always been a key technical problem that plagues engineers and technicians in evaluating the potential hazards of goafs and r...
