摘要/Abstract

摘要： 为了解水平错动作用下复杂构造的上覆岩层在井工开采服务年限内的应力应变情况,采用PFC3D作为模拟平台,基于下落法构造了该拟采矿区上覆岩层模型。该上覆岩层包含5层,其中有侵入火成岩,其下部岩层由于构造应力存在背斜和向斜构造。对长时间的岩层变形进行了模拟,并分析了这5层岩体在该过程中的应力应变特征。研究表明,错动产生的压应力贯穿该上覆岩层需要379年,并确定了压应力最强贯穿路径。对该模拟进行应用确定了穿过该岩层的最优巷道路径及井工开采服务年限与巷道建设位置的对应关系。

Abstract: In order to understand the stress and strain of the complex overlying strata with horizontal offset in service time of mining, the model of the overburden mining regions is created by PFM with the simulation platform of PFC3D. The overlying strata contains five layers including intrusive igneous rock, of which the bottom rock has anticline and syncline structure due to tectonic stress. The stress and strain characteristics of the five layers of rock mass are analyzed. Studies show that it takes the compressive stress 379 years to penetrate the overlying strata. The strongest penetrate path of the compressive stress is also determined. The simulation demonstrates the optimal path of roadway through the layer and identifies the correspondence between the service time of mining and the construction position of mining roadway.

Key words: well versed in mining, complex overlying strata, horizontal offset, damage development characteristics
