矿压显现明显区域综放工作面两巷平行控制测量技术

Parallel Control Survey Technology of Haulage Gateway and Return Airway on Fully-mechanized Top Coal Caving Face in Regions with Obvious Strata Behaviors

随着煤矿采深的不断加大,矿山压力的显现日趋明显,尤其是存在冲击地压的井田,测量导线点随时受到影响而变动。如何在矿山施工测量方面采取相应措施,保证综采工作面两巷的平行,确保回采工作的顺利进行,是需要研究的重点。通过工作面两巷施工过程中首先总结动压显现规律,在施工放线时对设计方向进行微量修正并及时进行联测验证,然后根据先施工巷道的偏移量调整后施工巷道。应用实践证明,该措施可行、可靠。

With the increasing of mining depth of coal mine,mine pressure appears obviously day by day,especially in the coal field with strata behaviors,traverse point is to be changed at any time due to its influence.How to take corresponding measures in mine construction survey to ensure the two roadways parallel on fully-mechanized working face,and ensure the progress of the mining needs to be studied.In this paper,strata behaviors laws were firstly summarized during the process of the two roadway construction on working face,the design direction correction was adjusted in detail when marking lines,test and certification were also taken in practice in time.At the end,according to the migration of roadway has been constructed,the roadway in follow-up process was adjusted while being constructed.Practice proves that this measure is feasible and reliable.
