Tectonophysical model of fault tectonic rock burst with wing sliding

为研究强冲击地压发生后断裂构造两侧的位移方向,建立了冲击地压的构造物理模型,从构造应力场的角度分析了断裂构造位移的从属现象,不属于开采技术性问题.通过对乌拉尔矿区和北票矿区的研究,确定开采扰动下,构造型冲击地压发生过程中,沿着断裂方向的位移矢量和开采技术间的相关性,主断层沿延伸方向的位移与构造应力场的存在相一致.通过对沿断层面的位移和构造应力场方向间的关系,以及孕育冲击地压的区域R范围和震源区尺度间的比率关系的分析,表明断裂翼部滑动型冲击地压是区域现代构造运动的结果,采矿工程活动是诱因.

In order to study the displacement directions of the both sides of fault tectonic after strong rock bursts, the paper established tectonophysical model of rock burst, and analyzed the dependent phenomenon of fault displacement from the view of the tectonic stress field, which does not belong to the mining technogenic. Through the study of Ural mining area and Beipiao mining area, this paper found out the correlationship between displacement vectors along faults and mining technology during tectonic rock bursts caused by mining. The displacement along major faults is consistent with the existence of tectonic stress field. The analysis of the relationship between the displacement of fault plane and the direction of tectonic stress field, as well as, the ratio between inoculating rock bursts R and source size, shows that the fault tectonic rock burst with wing sliding is the result of regional modern tectonic movement, and mining engineering activity is just the cause.
