Comprehensive survey method for large-span shallow-buried limestone goaf

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. 本发明公开了一种大跨度浅埋灰岩采空区综合勘察方法，涉及地下开采技术领域；该方法包括步骤：资料的收集、勘察场区的地质调查与测绘、勘察场区的专项调查、采空
