基于动量平衡密封装置的大孔径静态爆破掏槽试验研究

摘要

根据大孔径静态破碎膨胀压力测试结果，分析了大孔径静态破碎剂反应机理。基于动量平衡原理发明了新型大孔径静态破碎密封装置，并成功运用于模拟掏槽实践。结合掏槽实践实测数据，修正了孔间距近似计算公式。该技术对小净距交叉环境下掏槽工程具有一定参考意义。%According to the test results of expanding pressure of large borehole static cracking,the reaction mechanism of large borehole static cracking agent is analysed.Based on momentum balance principle, a new sealing device was invented and has been successfully applied to analogue cutting engineering practice.The hole-spacing approximate calculation formu-la is modified with test data of cutting practice.The technology has some reference to cutting engineering practice in condi-tions of small interval intersection.
