摘要
为降低大倾角开采工作面矿压显现规律复杂多变给矿井安全生产带来的安全隐患,文章通过现场实测数据和数值模拟相结合的方法,对工作面进行了模型构建及分析,并且研究了大倾角煤层开采过程中围岩破坏规律、顶板变形特征及矿压显现基本特征。通过实际矿压监测,可以发现工作面支架来压程度显著,各液压支架初撑力表现稳定,矿井作业安全性较高。
In order to reduce the hidden danger to mine shaft work safety caused by the complex and changeable mine pressure occurence law in the large dip angle mining face,this paper constructs and analyzes the model of the working face through the combination of field measured data and numerical simulation,and studies the failure law of surrounding rock,the deformation characteristics of roof and the basic characteristics of mine pressure occurence in the mining process of large dip angle coal seam.Through the actual mine pressure monitoring,it can be found that the pressure from the working face support is signifi cant,the initial support force of each hydraulic support is stable,and the operation safety in the mine shaft is high.
