运输顺槽沿顶掘进在厚煤层综放工作面的应用

The Application of Transportation Channel Heading along the Top in the Fully Mechanized Face of Thick Coal Seam

针对跃进矿在厚煤层开采时采用的运输顺槽沿煤层底板掘进带来的支护和维护问题,改用运输顺槽沿煤层顶板掘进技术并制定了锚杆锚索支护方案。现场监测结果表明:在采用运输顺槽沿顶掘进后,运输顺槽的变形量得到了有效的控制,支护和维护的成本显著降低,保证了矿井安全高效生产。

In view of the problem of support and maintenance brought by the transport CIS trough along the floor of the coal seam in the mining of Yuejin Coal Mine in thick coal seam,the technique of driving along the roof of the coal seam is used and the bolt and anchor cable supporting scheme is formulated.The results of field monitoring show that the deformation of the transportation grooves has been effectively controlled and the cost of support and maintenance is significantly reduced,and the safe and efficient production of the mine is ensured.
