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。 Taking the mine in western Beijing as the background, the shallow coal seams in the mine are basically finished mining, and the impact pressure is started below 800 m. Water, fire and gas disasters are not serious, but the impact of pressure is the focus of mine disaster phenomenon, the threat to mine safety is more and more. From theory to practice, the applicability of point load meter is demonstrated in two aspects, which provides a more efficient, convenient and reliable instrument and equipment for judging mine rock burst.
