田岗断层产状的确定方法

Method for identifying the occurence of Tiangang fault

搞清断层赋存状态对矿井安全生产至关重要。针对目前以范围表示方法确定断层产状存在精度不足的问题,山东崔庄煤矿通过在井下施工断层探孔,探明了田岗断层地质层位关系等情况,并运用平面投影法和矿体几何要素较准确地确定了田岗断层的产状要素,包括断层倾角、断层落差和断层走向等,从而取代了通常对断层产状较模糊的范围表示法。本研究方法原理简单,易于掌握,其计算结果比原有地质资料更加准确可靠。

It is critical to make clear fault occurrence for safe production in coal mines. Through drilling under- ground boreholes to detect a fault in Cuizhuang mine, the relationship of geologic horizon of Tiangang fault was identified. By using the geometric data and planar projection of the seam, the occurrence elements of Tiangang fault including dip, throw and strike were relatively accurately determined, replacing the ordinary vague extent representation of fault occurrence. The method used in the paper is simple in the principle, easy to master. Its cal- culation results are more accurate and more reliable than the existing geologic data. It provides technical support for realization of refined mining in coal mines and has reference value for mining areas with similar geologic and mining conditions.
