顾北煤矿1242(3)工作面作为提高回采上限的试采工作面,顶板破碎,矿压显现明显。为了顺利安全完成回采任务,制定了科学有效的矿压观测方案,分析出上提工作面矿压显现规律,并将之应用于生产。有针对性地采取了一系列措施加强顶板管理确保工作面较快推进,该上提工作面的开采经验,对类似地质条件的工作面回采有一定参考价值。
GuBei Coal Mine 1242 (3) Face As a trial mining face to raise the upper limit of mining, the roof is broken and the mine pressure is obvious. In order to complete the recovery task smoothly and safely, a scientific and effective observation program of rock pressure was established, and the law of occurrence of rock pressure in the working face was analyzed and applied to production. Targeted to take a series of measures to strengthen the roof management to ensure that the work surface to promote faster, the proposed mining face of the mining experience, similar to the geological conditions of the face mining has some reference value.
