煤矿立井基岩段涌突水事故统计分析及防治水建议
|
摘要
为了对煤矿井筒基岩段涌突水主控因素体系和涌突水危险性预测提供基础参考资料,对我国近年来煤矿井筒基岩段涌突水事故进行了统计分析,共收集基岩段涌突水案例21个。统计分析结果表明:煤矿井筒基岩段涌水水源按其涌突水事故次数在总事故中的比例从大到小排列依次为砂岩裂隙水、构造导水、岩溶水、松散层水、老空水;瞬时涌突水事故占总事故的61.9%,迟滞涌突水事故占到总事故的38.1%;而且采用地面预注浆后仍发生突水井筒明显少于采用工作面注浆的井筒。
To provide basic reference data for water inflow & inrush prediction and for the establishment of its key-control factors system for aquifers in the basement section of coal mine shaft,the present paper provided a statistical analysis of the water inrush & inflow accidents in the bedrock section for coal mine in recent years,and 21 accident cases were gathered. Outcome of the statistical analysis indicates that the inflow & inrush water could be ranked as fissure water in sandstone,conductive water from fault zone,karstic water,unconsolidated formation water and goaf water according to the ratio of its accidents in the total accidents,and the ratio of instantaneous water inflow & inrush accidents in the total accidents was 61. 9% while that is 38. 1% of the lagging water inflow & inrush accidents,and that the numbers of the water inflow & inrush shaft sealed by pre-grouting from the surface was less than that of the shaft took face grouting dramatically in addition.
