摘要
针对静态膨胀生裂技术问题,通过参考文献的实测数据和理论推导,得出静态膨胀剂可以膨胀裂开我国突出煤层。建立实验模型测试静态膨胀剂在突出煤体中的致裂效果。此次实验测试中,水泥槽实验模型突出煤体发生了裂隙发育、裂隙传播和裂隙扩展贯通3个明显变化过程。
Based on the issue of the static expanding and cracking,according to testing data of references and theoretical derivation,it is achieved that the static expansing and cracking can crack outburst coal seam. Establish empirical model to study crack effect of static expanding and cracking. This empirical model of cement tank show outburst coal through three obvious change process,that were occurred fracture,crack propagation and crack extension,indicating the static expanding and cracking effect by the free faceand the well location.
