摘要
根据杭来湾煤矿30101首采工作面开采条件,进行了室内物理相似模拟试验研究,并对工作面进行了矿压实测分析。确定了杭来湾煤矿工作面初次来压步距和周期来压步距;给出了工作面支架所需额定工作阻力;研究了工作面大小周期来压显现规律及上覆岩层垮落特征。
Similar physical simulation test is studied based on the 30101 first mining face mining condition of Hanglaiwan mine, and measured value of faces mine pressure is analyzed. The first weighting step distance of working surface and the periodic weighting step distance are determined. The support with the rated working resistance is given. The large and small periodic weighting behavior regularity of working face and the collapsing characteristic of overlying strata are studied.
