n,属于低瓦斯矿井。 根据井田地质条件,提出四个技术上可行的开拓方案。方案一:立井两水平开拓上下山开采,暗斜井延深;方案二:立井两水平开拓上下山开采,立井直接延深;方案三:立井两水平开拓上山开采,暗斜井延深;方案四:立井两水平开拓上山开采,立井直接延深。通过技术经济比较,最终确定方案三为最优方案。一水平标高-700 m,二水平标高-1000 m。 设计首采区采用采区准备方式,工作面长度150 m,采用综采放顶煤采煤法,矿井年工作日为330 d,工作制度为“四六制”。 大巷采用胶带输送机运煤,辅助运输采用矿车运输。矿井通风方式为中央并列式。 专题部分题目:松软破碎巷道注浆加固加护:煤矿软岩巷道工程是软岩工程的一个重要组成部分。软岩工程是指与塑性大变形岩体有关的岩体工程,如软岩边坡,软岩隧道及软岩巷道工程等。由于软岩巷道工程所处的复杂工程地质条件,其支护问题一直是困扰我国煤炭生产的一个主要问题。本文系统论述了软岩的定义、工程地质特征和力学属性,分析了软岩巷道围岩的变形破坏特征及影响因素;就注浆加固技术国内外研究现状及目前存在的问题进行分析探讨;深入分析了围岩锚注加固机理;最后对松软破碎巷道注浆加固技术工程应用进行了设计。 翻译部分题目:The applicatio
