摘要
针对陈四楼煤矿2705工作面的顶板情况,选择与本工作面相适应的液压支架,并对其支护强度进行验算,保证其满足支护要求,并对工作面矿压进行观测,对工作面支护质量等进行定期分析,并进一步了解煤、岩体力学参数等基础数据。有力地保证了工作面安全生产。
According to CHENSILOU coal mine 2705 working face roof, with the option of the working surface is adapted to hydraulic bracket, and the supporting strength is checked, to ensure that they meet support requirements, and the mine pressure observation, to face supporting quality rock mechanics parameters data base. A strong guarantee to conduct regular analysis, and further orking faces understanding of coal,
