【摘要】：井下钻探是煤矿日常生产中获取地质资料及消除安全隐患的技术手段。而现阶段煤矿生产中施工的钻孔多不进行钻孔轨迹测量,造成地质资料误判、安全措施客观上不到位的情况时有发生。为根本解决这一问题,根据钻孔轨迹测量原理研发出基于航姿参考系统的电磁波无线随钻轨迹测量系统。该系统具有成本低、方便应用的特点,且能满足无线随钻测量的要求。井下实验证明,该系统可以高效地完成随钻钻孔轨迹测量,提高钻进效率。
[Abstract]:Underground drilling is a technical means to obtain geological data and eliminate hidden safety hazards in daily production of coal mines. However, most of the boreholes in coal mine production at present do not carry out borehole trajectory measurement, which results in the misjudgment of geological data. In order to solve this problem, an electromagnetic wave wireless track measurement system based on attitude reference system is developed according to the principle of borehole trajectory measurement. The system can be used conveniently and can meet the requirement of wireless measurement while drilling. The experiment results show that the system can effectively measure the trajectory of drilling while drilling and improve the drilling efficiency.
