摘　　要： 放顶煤采煤技术运用广泛,但在开采推进过程中,采空区会发生冒落现象。当发生冒落时,采空区内的空气被迅速压缩,在巷道中形成强大气流,从而对井下人员造成危害。因此,要对发生冒落的工作面推进方位进行研究预测。本文运用FLAC3D软件,提出一种模拟冒落带演变的方法。以安家岭井工2矿4207工作面为例,对冒落带演变进行了模拟,成功的得出了冒落带演变规律。 Caving coal mining technology is widely used, but in the mining process, the mined-out area will be a phenomenon. When the creep occurs, the air in the mined-out area is quickly compressed, forming a strong airflow in the roadway, thus causing harm to the underground personnel. Therefore, it is necessary to carry out research on the prediction of the working face. In this paper, we use FLAC3 D software to propose a method to simulate the evolution of caving zone. Taking the 4207 working face of Anjialing Welling Coal Mine as an example, the evolution of the caving zone is simulated and the evolution rule of the caving zone is obtained successfully.
