韩城矿区构造控煤样式与构造控煤模式
|
摘要
为掌握韩城地区煤田构造变形特征和含煤地层赋存的规律,指导该区的煤炭资源勘查与评价,在系统总结韩城矿区地质构造发育规律的基础上,运用构造控煤分析方法,提出了矿区控煤构造样式,总结出矿区构造控煤模式。研究认为韩城矿区构造控煤样式共有3大类8种类型,其形成机制主要以挤压作用为主,辅以拉张和走滑作用。煤层赋存规律与控煤构造样式与模式密切相关,韩城矿区普遍存在聚煤前古构造控煤模式、同沉积构造控煤模式和后期构造控煤模式等3种构造控煤模式。综合韩城矿区地质构造发育机制,解释了韩城矿区东南浅部瓦斯含量高于西北深部的反常现象存在的原因。
To obtain the regularities of coal structure deformation and the occurrence coal-bearing stratum,and guide the exploration and evaluation of coal resources in Hancheng area,coal-control structural analysis method is used to conclude coal-control structural modes,based on the existing coal field geological prospecting data and systematic summary of coal field structural features. It is considered that the coal-control structural patterns were classified into three patterns and eight modes. The formation mechanism is mainly compression,complemented by extensional or strike-slip actions. The relation between coal measures hosting features and coal-control structural patterns and modes is very closed.There are three coal-control structural modes in Hancheng mine area such as paleostructure mode,synsedimentary structure mode and later structure mode. Based on the development mechanism of geological structure in Hancheng mine area,the reasons for the abnormal phenomena of gas content in the southeast higher than that in the Northwest Hancheng mine area are explained.
