Key experimental technologies and their development directions for the exploration and production of deep coalbed methane by Xia YAN, Fengyin XU, Xianyue XIONG, Feng WANG, Chunhu LI, Jiyuan ZHANG, Borui XU, Qianhui CHENG, Xiong HU, Xueguang ZHU, Wei LIANG, Pu YUAN, Yanqing FENG, Zhenji WEI

“…ProspectsThis study posits seven development directions for deep CBM production and in-situ coal conversion experiments: (1) Clear, direct observation techniques for micropores (< 2 nm) in deep coal seams with ultra-low porosity and permeability, full-scale pore size splicing technology for multiscale pore structure characterized by abundant micropores, a few mesopores, and many macropores, and assessment techniques for pore-fracture connectivity. (2) Isothermal adsorption test technologies for raw coals considering the effects of deep coal seam wettability, fracturing fluid invasion, and high total dissolved solids (TDS) under high-temperature, high-pressure in-situ conditions; (3) Sealed coring devices and in-situ pressure-retaining coring technologies featuring high pressure retaining success rates, heat preservation rates, and traceable gas volume. (4) Nanoscience-based assessment technologies for gas and water occurrence in micropores in deep coal seams under high-temperature and high-pressure multi-field coupling, and experimental technologies for desorption, diffusion, and seepage across nano-micro-millimeter scales. (5) Techniques for developing and testing multifunctional mechanical experiment equipment applicable to in-situ conditions of deep coal seams featuring high stress, low modulus of elasticity, and high Poisson's ratio. (6) Experimental techniques for the purpose of enhancing CBM recovery of deep coal seams, including reservoir stimulation (microwaves, laser, and electric heating), stimulation for permeability enhancement (electromagnetic pulses, pulsed ultrasonic waves, and controlled shockwaves), displacement via CO2 injection, and mechanical pulsation with supercritical CO2. (7) Experimental techniques for in-situ coal conversion and utilization, including pyrolysis, underground coal gasification (UCG), geothermal utilization, and CO2 geological storage. …”

Characteristics of the Volunteer Service Management System for National Parks in the United Kingdom by Tianyi REN, Chuanbo HONG, Yinglin WANG

“…Meanwhile, on the basis of literature review, this research searches relevant official data on the first batch of national parks announced in China, analyzes such contents as management documents, activity management, and personnel recruitment management, and compares the same horizontally with the volunteer service management system for national parks in the UK so as to analyze the shortcomings of the volunteer service management system for national parks in China and put forward corresponding suggestions.ResultsThe research finds that the 14 national parks in the UK have sound volunteer service management policies, management system structures and volunteer recruitment websites, as well as open and transparent volunteer screening mechanisms and volunteer feedback channels. …”

Integrated Framework and Technical Path for Multi-level Nested Assessment of Landscape Character by Yuncai WANG, Qizhen DONG

“…The overall landscape carries the overall humanistic ecosystem, whose structurality and decomposability determine that landscape space is a complex composed of multiple relatively independent spaces, concatenation and nesting determine the multi-level nesting of the overall landscape space, and perceptibility and symbolism determine that identifying the characteristics of a landscape is a way to recognize the unique value of the landscape. …”
