摘要

综放开采因其能将煤炭资源迅速转化为生产力的优势而得到广泛应用。巴彦郭尔煤矿水资源匮乏,植被覆盖率低。综放开采条件下覆岩流水裂隙带的演化是未知的,对生态环境的影响也无法预测。因此,本文以311101工作面为研究对象,采用理论分析、FLAC3D数值模拟等方法,对巴音郭尔煤矿综放开采中流水裂隙带演化进行了研究。通过多种方法的综合应用,确定了311101工作面流水裂隙带发育高度,初步揭示了巴彦郭尔煤矿综放开采覆岩流水裂隙带演化规律,为后续工作面开采提供了指导和参考。

Simulation research of water flowing fracture zone of overburden strata in fully mechanised caving mining
Fully mechanised caving mining is widely used because it can quickly convert coal resources into productivity advantages. The water resources of Bayangol coal mine is scarce and the vegetation coverage rate is low. The evolution of the water flowing fracture zone in overburden strata under the fully mechanised caving mining conditions is unknown, and the impact on the ecological environment cannot be predicted. Therefore, this paper took the 311101 working face as the research object, adopted theoretical analysis, FLAC3D numerical simulation and other methods to carry out the study on the evolution of water flowing fracture zone in fully mechanised caving mining in Bayangol coal mine. Through the integrated application of different methods, the development height of the water flowing fracture zone of 311101 working face is determined, and the evolution of the water flowing fracture zone in overburden strata of the fully mechanised caving mining in Bayangol coal mine is preliminarily revealed, which provides guidance and reference for the subsequent working face mining.
