摘　　要：采用现场监测的方法对某矿大采高综采放顶煤601首采工作面矿压显现规律进行监测，通过对监测数据进行分析，揭示了该矿601综采工作面的矿压显现规律，得出该工作面的初次来压步距平均为35 m左右；周期来压步距为22．95～27．20 m，平均为25．2 m，来压时间为2 d。该工作面直接顶呈现分层垮落：下部泥岩先垮落，上部粗砂岩直接顶后垮落，初次垮落步距16．75 m左右。研究结果对该矿其他工作面开采设计和巷道、切眼的支护参数优化设计具有参考价值。Monitoring was conducted on the ground behavior law in 601 fully-mechanized first-mining caving face with largemining height in a mine by using the site monitoring method. Through the analysis of the monitoring data, the ground behavior law of601 fully-mechanized face was revealed, and it was found that the mean distance of the first weighting in this face was about 35 m, themean distance of the periodic weighting was 22.95 - 27.20 m, 25.2 m on an average, and the weighting time was 2 days. Theimmediate roof of the face caved layer by later, the lower mudstone layer caved first, and then the upper grit layer, the distanceof the first caving was about 16.75 m. This research result has a reference value for the mining design of other faces and theoptimization design of support parameters of roadways and starting cuts in this mine.
