The invention discloses a mine high and steep slope landslide machine learning prediction method based on an unmanned aerial vehicle technology and multi-source data fusion. The method comprises the steps that a high-resolution digital surface model is shot by an unmanned aerial vehicle; removing non-topographic features from the digital surface model data in ArcGIS software, then converting the digital surface model data into digital elevation model data, obtaining a surface refining model of the surface mine in the digital elevation model, taking the surface refining model as a constraint to trim the surface of the three-dimensional geologic model, and fusing factors of ArcGIS software and three-dimensional geologic model analysis by using Python to obtain a three-dimensional geologic model surface refining model; complete slope data are constructed; inputting the fused complete side slope data into a machine learning algorithm training model, and generating a side slope landslide susceptibility prediction model; the optimized model is used for carrying out landslide susceptibility prediction on new slope data. According to the method, various factors influencing the slope stability can be comprehensively analyzed, high efficiency can be kept during large-scale data processing, and the slope stability in mine engineering can be evaluated more accurately.

The application is a kind of exhibition hall ground ditch inside electromechanical comprehensive pipeline assembly type construction method, which comprises the following steps: electromechanical comprehensive pipeline module division, main pipe ditch support design, branch pipe ditch support design, factory prefabrication, factory or ditch edge assembly, segmented hoisting and segmented installation, positioning adjustment support fixing, alignment connection between alignment sections, fire hydrant box and comprehensive box installation. The method is beneficial to the rapid and reasonable construction of the exhibition hall ground ditch inside electromechanical comprehensive pipeline, the designed pipe ditch support realizes the purpose of factory prefabrication and on-site assembly type construction, and solves the technical problem that the construction of the electromechanical comprehensive pipeline in the exhibition hall ground ditch is relatively difficult due to the narrow space. In addition, the fire hydrant box in the method is newly designed in the principle of convenient use, and can be directly pulled up when needed, which is simple to operate and convenient to use. Practice proves that the method is safe and reliable, convenient to construct, and good in appearance, and achieves the expected index and target.

This invention relates to the technical field of tunnel construction methods, and in particular to a method for anchoring and pulling out anchors in the excavation section of a hard rock tunnel. The method includes the following steps: S1, setting the outline of the excavated rock mass and creating a weakened structural surface along the outline; S2, driving several anchor rods into the excavated rock mass and creating a rock mass structural surface with several anchor rod ends; S3, using construction machinery to pull out the anchor rods; S4, removing slag; S5, subsequent rock mass support. This invention features simple process steps, a reasonable design, convenient construction, and good performance. It can easily complete the excavation and construction process of hard rock tunnels, ensuring safety and guaranteeing the construction period.
