基于孔型组合的煤矿水害区域治理模式研究
|
摘要
为了提高水害区域治理技术的适用性,优化治理工程布置,从钻孔形态组合的角度研究煤层底板水害区域治理模式分类方法。以邢台矿区区域治理工程为例,介绍了包括地面定向钻进、地面径向射流和井下定向钻进在内的综合钻进技术,分析了地面条件、采掘工程条件和治理层特征等多种布孔影响因素,划分了不同主孔形态和分支类型,提出了基于不同孔型组合的水害区域治理模式分类方法。研究结果表明:区域治理方案制定时,选用经济可行、技术合理的钻进技术,通过不同类型的孔型组合,可以实现整个治理区的全覆盖;区域治理模式分类方法可以建立适用于浅部构造发育区加固、中深部形态复杂区改造、深部多分区探查等多种条件的水害区域治理技术体系,为华北型煤田水害区域治理工程设计提供参考。
In order to improve the applicability of water hazard regional control and optimize the borehole group layout,coal floor water regional control pattern classification method was studied based on different borehole group type. Xingtai mining area regional control engineering condition was introduced as the study background.Integrated drilling technology including surface directional drilling,radial jetting and underground directional drilling was studied to form different types of main boreholes and branch boreholes. Borehole layout is controlled by multiple influencing factors including ground condition,mining engineering and target layer characteristics.Water hazard regional control pattern classification method was established based on integrated drilling,influencing factors and borehole types.When regional control plan was formulated,economically feasible and technically reasonable drilling technology should be selected to comprehensively cover the entire control region by different types of borehole combinations.Based on the pattern classification method,shallow structural development area strengthening pattern,morphologic complex area transformation pattern and deep multiple areas detecting pattern were established.Research results can provide a reference for mine water regional control engineering design in north China.
