CN-121998454-A - Method for selecting ecological restoration grading exploration means of historical abandoned mine

Abstract

The invention discloses a method for selecting a grading investigation means for ecological restoration of a historical abandoned mine, which belongs to the field of ecological restoration of the historical abandoned mine, comprehensively determines investigation grades according to ecological problems, restoration directions, complexity of geological environment conditions and restoration modes in an investigation range, the different investigation grades correspond to different types of investigation means to select combinations, so that engineering personnel in the field can pertinently select the investigation means combinations according to the specific conditions of the abandoned mine, and the investigation work investment waste is avoided, or the investigation work investment is insufficient to influence the subsequent ecological restoration measure design.

Description

Method for selecting ecological restoration grading exploration means of historical abandoned mine Technical Field The invention relates to the field of ecological restoration of historical abandoned mines, in particular to a method for selecting a hierarchical exploration means for ecological restoration of the historical abandoned mines. Background The historical abandoned mine is a mine which is formed by historical reasons or policy adjustment and does not carry out exploitation activities, ecological restoration work is needed to be carried out according to local conditions in order to promote harmonious symbiosis of people, exploration is needed before ecological restoration measures are implemented, means adopted by exploration include remote sensing investigation, ground investigation, topographic map measurement, engineering geological mapping, exploration, sampling, testing and the like, and the purpose of the exploration is to find out natural geographic conditions, ecological environment conditions and ecological problems and provide basis for ecological restoration measure design. The accurate selection of the investigation means is a precondition for fine investigation, but the current conditions of different historical abandoned mines have great difference, and one investigation means cannot be commonly used, and the existing method selects one or more kinds according to working experience and has strong experience dependence, so a more definite investigation means selection method is needed, and the selection of engineering personnel in the field is facilitated. Disclosure of Invention The invention aims to solve the technical problems and provides a method for selecting a grading exploration means for ecological restoration of a historical abandoned mine. In the investigation range, the investigation grade is comprehensively determined according to the ecological problems, the repair direction, the complexity of geological environment conditions and the repair mode, and different investigation grades are selected and combined corresponding to different types of investigation means, and the aim is achieved by the following technical scheme: Step 1, determining a investigation range, namely determining the investigation range through a historical mining activity influence range and an ecological restoration measure related range; Step 2, in the investigation range, according to the analysis of the data acquired in the earlier stage, carrying out investigation grade division according to the ecological problems and the ecological problem grade, specifically: If the ecological problem level is level III, the investigation level is level III; If the ecological problems are level II and level I, the ecological problems are further analyzed according to the ecological problems, namely, firstly, if the ecological problems are all other ecological problems, the investigation level is level III, secondly, if the ecological problems comprise geological safety hazards, the ecological problems are further analyzed according to threat objects of the geological safety hazards, if the threat objects are ecological environments, the investigation level is level III, if the threat objects are personnel or facilities and the threat level is smaller, the investigation level is level II, if the threat objects are personnel or facilities and the threat level is larger, 2 cases need to be subdivided, wherein the first case is level I of the ecological problems, the investigation level is level I of the first case, the second case is level II of the ecological problems, the investigation level is determined according to ① that geological safety problems exist only and no geological disasters exist, the investigation level is level II, and the investigation level ② is level I. Further, the ecological problems described in step 2 are classified into 2 categories, namely geological safety hazards and other ecological problems; The geological potential hazards are classified into 2 types, wherein the first type refers to geological disasters possibly suffered in the investigation range after ecological restoration measures are implemented; Wherein, the geological disasters refer to collapse, landslide, debris flow, ground subsidence and ground cracks; wherein, the geological safety problem refers to dangerous rock mass, unstable slope, surface cracking and the like; The ecological problem level in the step 2 is divided into a level I, a level II and a level III, and when the ecological problem level is determined according to the geological potential safety hazard, the ecological problem level is determined to be the level III if the geological potential safety hazard does not exist in the investigation range, and the ecological problem level is determined to be the level II if 1 geological safety problem or stable small geological disaster exists in the investigation range; further, the investigation grade is divided
