河南省赵案庄式铁矿区地质构造和“山字型”构造的研究

The research on "山" characters type constraction system of zhaoan village iron deposit in henan province

赵案庄式铁矿是我国最早的铁矿类型之一,现正在地采.在开采过程中,由于地质构造复杂,地下水丰富,再加上存在软弱岩层,地压活动频繁,使得开采难度较大.为了指导生产及安全,通过查阅资料、野外勘查、理论分析,初步掌握了矿区大地构造和地质构造情况,确定了矿区存在"山字型"构造.本文分析了赵案庄式铁矿区地质构造和"山字型"构造的分布特点,指出了地质构造和"山字型"构造对矿床的破坏作用及对矿床开采的影响.

Zhao Anzhuang iron deposit is at Henan provice wu Gang city, It is developmented now. Because its geotectonic is very com- plex,so the production has been weakend. In order to raise the production,we need to research the geotectonic. The paper analysis the geotectonic feature and the“山”Characters type Constraction system of Zhanoan village iron deposit ,point out the disconstraction of the geotectonic and“山”characters type constraction system to the deposit, and the effect to the ore mine.
