等高四架法在禹州枣园煤业-80集中回风巷贯通测量中的应用

Application of Accordant Four-frame Method in the Cut-through Construction in-80 Concentrated Air Return Way of Zaoyuan Coal Industry

为确保矿井大型贯通工程的顺利、准确完成,采取有效措施,改进井下控制测量方法,成为矿山测量工作者面临的一项共同的重要课题。本文以枣园煤业-80集中回风巷贯通工程为实例,提出等高四架法,简述其工艺流程、操作要点,并与传统方法分析比较,具有操作简便、成果精度高、作业时间短的特点。

In order to ensure the smooth and accurate completion of the large cut-through construction in the mine, taking effective measures and improving the control survey method under the shaft has become a common important subject for mine surveying workers. This paper takes the cut-through construction in -80 concentrated air return way of Zaoyuan Coal Industry to put forward the accordant four- frame method, and briefly describes its technological process, key operating points, and compares it with the traditional method. The method has many characteristics, such as simple operation, high precision, short operation time and so on.
