    “Locality – Adaptation” Research of Hydropower Resettlement Communities in the Jinsha River Basin: A Case Study of Ludila Hydropower Station by Fang WANG, Zhuoqi LI, Haoyi XU, Jiaqi YAN

    Published 2025-04-01
    “…At the settlement scale, the Mask Region-based Convolutional Neural Network (Mask R-CNN) deep learning model is utilized to identify architectural spatial features, categorizing three typical building types: traditional pitched-roof buildings, uniformly planned flat-roof buildings, and color steel plate-modified structures. Through multi-source data fusion (including remote sensing, demographic statistics, and compensation records) and field investigations, the research quantitatively analyzes the “locality – adaptation” reconstruction process of resettlement communities across the three spatial dimensions of living, production, and cultural spaces.Results1) Land cover evolution: Water storage of hydropower station inundates 37.12 km2 of land (including 21.61 km² of high-quality cultivated land), resulting in a loss of 43.68% of settlement production space. 2) Adjustment of architectural space: 65.8% of dwellings in the original villages are traditional timber-earth buildings with a tile roof, which adapt to the climate environment of concentrated rainfall and sufficient sunshine in the Jinsha River Basin. 48.7% of the resettlement sites adopt unified flat roof planning, and 51.3% realize functional optimization through self-construction or renovation, with the average renovation area reaching 230.9 m2. 3) Transformation of livelihood system: The annual compensation mechanism only restores 15.79% of the cultivated land allocation before resettlement, and the proportion of compensation income drops from 82.71% in the initial stage of relocation to 33.15% after long-term resettlement, driving the adjustment of crop structure to high value-added cash crops. 4) Cultural space reconstruction: In the context of the disappearance of traditional water transport functions, the three cultural relics reconstructed in different places show a symbolic turn. …”

    Key technologies of efficient extraction of coalbed methane (gas) in Guizhou coal mine area by Wang YI, Longjun LIANG, Lichong YAN, Zhihua YAN, Jie CHEN, Wei GAO, Yi LOU, Fuqin YANG, Haiyang HU, Jiawei ZHU

    Published 2025-03-01
    “…It innovated and explored the following high efficiency extraction technology of “four zones” linked Wells in coal mining areas with Guizhou characteristics: ① By laying multi-functional pumping vertical Wells or small inclination oriented Wells in the goaf, it was the first time in Guizhou to realize efficient extraction and development of pressure relief gas in the overlying coal-covered strata and coal-bed methane in the sweet coal seam below the goaf; ② Taking advantage of the characteristics of spatial and temporal dislocation in the production area, the multi-mode extraction mode of “coalbed methane well + relief well + underground drilling” is adopted for the first coal seam mined in the upper protective layer, which realizes the purpose of the upper and lower vertical combined extraction of coalbed methane (gas) Wells and effectively solves the problem of multi-source gas flooding into coal mining roadway and gas accumulation in the upper corner during coal mining under the condition of coal seam group development in Guizhou; ③ In the preparation area and planning area, combined with the terrain and geological characteristics of the two areas, the horizontal well “well factory” + “two pairs of right and wrong” overlapping well layout mode is adopted to realize the efficient extraction of coal bed methane in the plane in advance and pre-pumping of the sweet coal seam and the pressure relief gas in the overlying coal-laden rock in the subsequent mining process, and at the same time to achieve the goal of “replacing the roadway with Wells”; ④ In view of the development of multi-thin coal seam groups in the study area and the development characteristics of “three zones” in the overlying strata after mining, due to the continuous change of the role of “four zones”, the surface coalbed methane Wells are initially deployed in the production area or preparation area, and the “bridge plug bottom sealing + layer selection perforation” technology is adopted to innovate the “transformation” technology of well structure to achieve the purpose of “multi-purpose in one well”; It also provides new technical ideas and accumulated valuable engineering experience for gas management in coal mine area under the condition of multi-thin coal seam group development in Guizhou.…”
