哈拉沟煤矿四盘区首采面矿压规律分析

摘要

Mine pressure observation was carried out in first mining face of Halagou coal mine.Based on the mine pressure observation,the paper analyzed the relationship between bedrock breaking,water inrush and sand inrush with strata behavior regularity.The result can provide science experience for preventing water inrush and sand inrush and water-preserved mining in coal mining.%通过对四盘区首采工作面矿压观测,揭示了工作面初次来压和周期来压的基本规律,分析了基岩破断、溃水溃沙与来压规律的关系。为工作面防止溃水溃沙、实现保水开采提供了经验。
