摘　　要：以京西某矿为背景,该矿浅部煤层基本采完,800 m以下开始有冲击地压现象。水、火、瓦斯灾害不严重,而冲击地压是矿井重点灾害现象,对矿井安全生产的威胁越来越大。从理论到实践两方面论证了点荷载仪的适用性,为判断矿井冲击地压提供了一种更为快捷、方便、可靠的仪器设备。Based on the background of Jingxi mine, the basic picking shallow coal of this mine has been mainly mined,there is the ground pressure phenomena under the 800 m. Water, fire, gas disaster without serious impact but ground pressure is central to the mine disaster phenomenon, the threat to the mine safety production is more and more big. From two aspects of theory actually realized practice demonstrates the applicability of the point load tester, to judge the mine bumps provides a more quick,convenient and reliable equipment.

关 键 词：冲击地压 点荷载仪 高应力集中区域 岩石强度
