摘要:
为了更好的研究各因素对30108工作面矿压规律的影响程度,在矿压现场观测工作的基础上,文中采用3DEC模拟软件对杨伙盘煤矿30108综采工作面开采过程中顶板破坏情况进行分析,并用FLAC3D软件进一步对矿压显现规律进行模拟研究,结果表明3-1煤层的冒放性比较好,基本顶来压明显,上覆岩层中形成的压力拱结构可以减缓地表松散层与基岩层的同步下沉运动对工作面回采空间的影响。
Abstract:
In order to study how different factors influence the mine pressure regularity of the 30108 working face, this article makes use of 3DEC software to analyze the situation of the roof's damage in the mining process of the fully-mechanized face in Yanghuopan colliery, based on on-site mine pressure, and also uses FLAC3D simulation software to simulate mine pressure behavior law. The result of analysis shows that the caving property of coal seam is comparatively well, basic roof pressure appears obviously, the stress arch structure formed in superincumbent stratum can slow down the effect of the extraction space caused by the synchronous sinking motion of the incompact surface and the bedrock layer.
