摘 要:针对近急斜综采工作面的开采现状,利用RFPA数值计算系统模拟软件对近急斜综采工作面数学模型进行了模拟计算,得到近急斜煤层沿着煤层倾斜方向因为充填的差异,中上部顶板压力较大,下部顶板压力较小的结论。在实际工程中,需对顶板进行强制处理,减小来压步距,降低来压强度,从而保证生产的安全进行。In view of the current mining situation of the nearly steep fully mechanized mining face,this paper simulated the mathematical model of the nearly steep fully mechanized mining face by using the software of RFPA numerical calculation system.The conclusion was drawn that the pressure of the middle and upper roof was larger and the pressure of the lower roof was smaller due to the difference of filling along the inclined direction of the coal seam.In practical engineering,the roof should be treated compulsively to reduce the pressure step and the pressure strength,so as to ensure the safety of production.
