卸压开采抽采瓦斯理论及煤与瓦斯共采技术体系

针对低透气性、高吸附性、高瓦斯煤层群安全高效开采技术难题，以淮南矿区为主要试验研究基地，应用岩石力学、岩层移动、“O”形圈、瓦斯流动等理论，研究卸压开采采场内岩层移动及应力场分布规律、裂隙场演化及分布规律、卸压瓦斯富集区及运移规律等科学规律.针对不同煤（岩）层和瓦斯地质条件，探索出卸压开采抽采瓦斯理论，建立了卸压开采抽采瓦斯、煤与瓦斯共采技术体系.创新了低透气性、高瓦斯煤层群安全高效开采矿井设计理论，解决了煤与瓦斯共采重大工程技术难题.

Theory of pressure-relieved gas extraction and technique system of integrated coal production and gas extraction

To resolve the problems of safe and high-efficient mining of gassy multi-seam of low permeability and high absorbability,based on the theories of rock mechanics,strata movement,O-type circle and gas movement,and taken Huainan mining area as main research base and studied rock movement and stress field distributing theory,cranny field evolvement and distributing theory,abundant zone of pressure-relieved gas and movement theory.Discovered pressure-relieved mining and gas extraction theory,built the technical ...
