新疆克孜勒布拉克煤矿矿区构造特征及深部探矿思路

Structural characteristics and deep prospecting idea of the Kizil Bulak coal mine in Xinjiang

克孜勒布拉克煤矿位于天山南麓、塔里木盆地北缘,库车—拜城煤田中部。矿区地质构造类型复杂,褶皱构造对深部煤层形态影响较大,煤层深部形态受褶皱构造控制,致使深部煤层控制难度大。通过对矿区构造特征及深部煤层赋存规律的综合研究分析,根据探矿工作中存在的一些实际问题,提出矿区深部探矿工作采用坑探结合巷内钻探的思路,既可以有效控制矿体的空间形态,又可降低探矿成本、减小探矿工作对环境的破坏。

The Kizil Bulak coal mine is located in the south of the Tianshan Mountains and north of the Tarim Basin, and is in the middle of the Kuqa-Baieheng coal field. Geological structures are complex in this coal mine, of which fold structures exert a major influence on the shape of deep coal seams. The shape of these seams is controlled by these fold structures, and it is thus difficult to determine the deep seams in this area. This work comprehensively analyzed the structural features of the mine and the occurrence rules of deep coal seams, and proposed a deep prospecting idea of ＂integrated tunnel engineering with laneway prospecting＂, based on the practical problems of drilling. This idea can effectively control the spatial shape of orebodies, and can also reduce drilling cost and damage on the environment.
