摘要
通过对东三采区薄煤层首采工作面7501矿压观测,弄清了该面在回采过程中矿山压力显现规律,为同采区相邻工作面回采期间的顶板压力预测预报和来压期间的顶板控制提供依据。
In accordance with mine pressure survey of 7501 the first work face of thin coal seam＇in DFH--3 mining area, the author explains strata--pressure behavior in the mining course, which provides basis for roof pressure forecast during the period of mining in the same mining area of adjacent face and roof control in weighting period.
