承压水上采煤学科理论与实践

基于８年现场观测实践、大量的第一手资料分析和综合的理论试验研究，提出建立承压水上采煤学科领域──采动岩体水力学。阐明其理论基础──基本定理、原理及规律；形成其研究内容与方法──预测、观测、治理与监测及开采系统工程；组成学科综合研究体系。该学科可有效地阐明承压水上采煤的采动应力场与承压水运动场耦合效应的底板突水机制，合理设计防治措施等有关问题，为矿井安全生产起到积极作用。

THEORY AND PRACTICE OF COAL MINING DISCIPLINE ON CONFINED WATER

Based on field observations, large quantity of first hand information and theoretical research made in the past eight years a discipline realm of coal mining on the confined water, namely, mining rockmass hydromechanics was established. The paper describes the theoretical basis, i. e., the basic theorem, principles and rules;the research contents and method, i. e., prediction, observation, control and monitoring of water inrush,as well as mining system engineering and comprehensive research system of the discipline. The research describes the mechanism of water inrush from the floor due to coupling effect of stress field resulted from coal mining on the confined water and movement field of confined water as well as problems relevant to adequate design and measures for prevention and control of water inrush, which plays an active role on ensuring safety in production.
