底板强含水层、高瓦斯等复杂的地质条件严重影响了平煤四矿庚20-21040工作面的掘进速度。通过科学的理论分析,采取开采前超前疏放和并行疏放及掘进中边探边掘、长探短掘、物探及钻探相结合的方法,成功了消除了寒武系灰岩岩溶裂隙水对巷道掘进安全的威胁,同时制定了专项防突、过断层等措施,实现了工作面安全、快速掘进。 Bottom aquifer, high gas and other complex geological conditions have seriously affected the Pingdingshan G # 20-21040 mining face. Through scientific theoretical analysis, taking the methods of pre-mining, drainage and parallel drainage and excavation of middle-side exploration and excavation, long-term exploration and exploration, geophysical exploration and drilling, the successful elimination of the karstification fissure water of Cambrian limestone Tunneling safety threats, while the development of a special anti-sudden, over the fault and other measures to achieve the face safe, fast heading.
