A reasonable mining scale is very important for the development of mining areas. In view of the lack of water resources in arid and semi-arid areas, this paper studies the scale of coal mining in arid and semi-arid areas under the constraint of the water resources carrying capacity (WRCC) with the aim of realizing the conservation mining of ecological environment. From the perspectives of market demand side, production side and the constraint side, a "trinity" decision model was constructed to investigate the main factors influencing the scale of coal mining. By introducing the optimal control theory with profit taken as objective function, the coal price and coal reserves were regarded as boundary conditions, and WRCC was set as constraint condition. Based on H-J-B equation algorithm, the decision-making equation for mining scale under the constraints of market demand and WRCC was obtained. Through comparing the mining scales under the two constraints, the mode of "water-based mining scale" was formulated, which is conductive for realizing the balance between coal mining and ecological environment development.
合理的矿业规模对矿区的发展非常重要。针对干旱半干旱地区水资源短缺的问题，本文以水资源承载能力（WRCC）为约束条件，研究干旱半干旱地区煤炭开采规模，旨在实现生态环境的保护性开采。从市场需求侧、生产侧和约束侧三个方面，构建了“三位一体”的决策模型，探讨影响煤炭开采规模的主要因素。通过引入以利润为目标函数的最优控制理论，将煤炭价格和煤炭储量作为边界条件，将 WRCC 作为约束条件，基于 H-J-B 方程算法，得到了市场需求和 WRCC 约束下的开采规模决策方程。通过比较两种约束下的开采规模，提出了“水基开采规模”模式，有利于实现煤炭开采与生态环境发展的平衡。
