摘要
根据沁水盆地东北缘新元煤矿的地质资料,构建矿井构造复杂程度综合指数模型。基于断层和褶曲构造数据,采用网格覆盖法计算分维值,生成构造复杂程度分区图。结果表明,构造复杂区呈NW-SE向展布,集中于井田西北部和中东部;断层网络分维值可综合反映断裂条数、长度及组合型式对复杂程度的影响;矿井整体构造类型属简单类,但复杂区需优化采区布局。研究成果为构造控采提供了量化依据,指导矿井向南部简单区延伸开采。
According to the geological data of Xinyuan Coal Mine in the northeastern margin of Qinshui Basin,a comprehensive index model of mine structural complexity was constructed.Based on the fault and fold structure data,the fractal dimension value was calculated by the grid covering method,and the structural complexity zoning map was generated.The results showed that the structural complex area was distributed in NW-SE direction,concentrated in the northwest and central east of the well field;the fractal dimension value of fault network could comprehensively reflect the influence of the number,length and combination type of faults on the complexity.The overall structural type of the mine was simple,but the complex area needed to optimize the layout of the mining area.The research results provided a quantitative basis for structural control mining and guided the mine to extend mining to the southern simple area.
