深井爆破作为人工震源时的施工工艺与激发效果探讨

Research on the construction technologies and stimulation results of deep well explosion as artificial epicentre

利用深井爆破作为人工地震可控震源时,会经常出现药量大的炮点爆破效果并不一定更好的现象.而有时候小药量的炮点却偶尔能接收到非常好的数据.作者结合多年实际工作中遇到的各种情况,归纳总结了几点当震源药柱作为人工震源时,影响深井爆破功效的可能原因.同时根据工作经验结合真实事件,对深井爆破作业的不同环境和不同施工工艺对数据采集效果的影响做出了自己的判断.

It was observed that,when deep well explosions were used as artificial epicentre,shotpoints with more explosive did not necessarily yield better results.However,shotpoints with less explosive could occasionally produce very good results.In this paper,with summarizing different conditions encountered during past years,the author concluded several possible reasons that using seismic charge as artificial epicentre may impact the effectiveness of deep well explosions.In addition,with combining real life experience,the author also provided his own judgments on the impact to data collection results from different environments and construction technologies of deep well explosions.
