强烈动压影响下锚网支护巷道矿压显现规律研究

Study on Ground Pressure Behavior Law of Roadway Supported by Anchor Mesh under Strong Dynamic Pressure

随着我国特厚煤层开采技术的广泛应用,特厚煤层中相邻的工作面对回采巷道具有强烈的采动影响,必须有相应的巷道支护技术保证回采巷道的稳定。通过强烈动压对锚网支护巷道矿压显现的影响进行研究,得出巷道矿压显现的规律,为特厚煤层巷道的锚网支护提供科学的理论依据。

With the extensive application of extra-thick coal seam mining technology in China,the adjacent working faces in extra-thick coal seam have strong mining influence and there must be corresponding roadway support technology to ensure the stability of mining roadway.Through the study of the influence of strong dynamic pressure on the mine pressure behavior of roadway supported by anchor net,the mine pressure behavior law of roadway is obtained,which can provide a scientific theoretical basis for the anchor net support of roadway in extra-thick coal seam.
