In order to perfect the theoretical system of "tectonic control of hazard", this thesis researches the control function of stratum inclination of monoclinic structure, fold shape and angle between two limbs of fold, normal fault direction of dip and fault inclination, forms of faults combination over coal-mining-induced subsidence by means of theoretical analysis and numerical testing.

为了进一步完善&构造控灾&理论体系，本文从典型煤矿区的地质条件和开采实际出发，在以往研究成果的基础上，通过理论分析和计算机数值试验，重点研究单斜构造的地层倾角、褶皱构造形态及其翼间角、正断层倾向和倾角及断层组合对采煤沉陷的控制作用。

Moreover, second-winding current waveform of a current transformer is calculated under the transient current of the typical short-circuit fault by numerical method. The analysis shows that the relevant protection equipment may refuse to trip when the fault current is extra high. It will result in the maloperation of protective relays for loss of their selectivity, and cause other protective relays to operate beyond range, and extend the scope of shutdown of power supply.

在这些回路出口处发生相间直接短路等严重故障时，流过相应TA一次侧的故障电流可能达到TA额定工作电流的100倍以上，大大超过了保护用TA的10%误差容许倍数，将使TA严重饱和，从而影响相关的保护设备的动作性能，因此有必要对在这种特大电流作用下的TA的传变特性做一些探讨，以分析其对继电保护装置动作特性的影响及应采取的措施。
