Core Viewpoint - The project "Gold Mine Survey and Evaluation in the Delbur-Morodaga Area of Inner Mongolia" successfully implements a "zero disturbance exploration" approach, balancing drilling activities with ecological protection [7][9]. Group 1: Project Implementation - The project team shifted from traditional trenching to small-angle drilling to minimize surface disturbance and protect the fragile grassland ecosystem [5][7]. - A portable hydraulic modular drilling rig was used, reducing the surface area impact to one-fifth of traditional rigs, with temporary access paths less than 2 meters wide [5][6]. - Environmental protection measures included using a fixed spray system to reduce dust during drilling and implementing a mud circulation treatment process [6][8]. Group 2: Technological Innovations - The project introduced a series of "green drilling" technologies, transforming the previous "ground disturbance" into "zero disturbance" exploration [7]. - The first small-angle drilling achieved a drilling angle of less than 30°, increasing the contact area with the borehole wall by over 40% and enhancing drilling efficiency [8]. - The project team utilized a low center of gravity and high torque drilling platform, along with a directional drilling system, to ensure stability and reduce vibration during drilling [8]. Group 3: Community and Ecological Impact - The project aims to integrate geological exploration, ecological restoration, and rural revitalization, focusing on resource security and regional development [9]. - Collaboration with local herders led to the signing of a vegetation restoration agreement, improving soil quality and guiding agricultural practices [9][10]. - Post-project, the grassland yield in the drilling area increased, benefiting local herders' income through improved crop suggestions [10].
