设计主要内容和要求： 按照采矿工程专业设计大纲要求，完成一般部分小鱼沟煤矿1.2Mt/a新井设计和专题部分煤矿开采冒落区注浆充填量预计研究，英译汉中文字数3000以上。 摘要 本设计包括三个部分：一般部分、专题部分和翻译部分。 一般部分为小鱼沟煤矿1.2 Mt/a新井设计。一般部分共包括10章：1.矿区概述及井田地质特征；2.井田境界和储量；3.矿井工作制度及设计生产能力、服务年限；4.井田开拓；5.准备方式-带区巷道布置；6.采煤方法；7.井下运输；8.矿井提升；9.矿井通风与安全技术；10.矿井基本技术经济指标。 小鱼沟井田位于准格尔煤田东北隅，井田东西长约3.8km，南北宽约3.0 km，面积约11.4km2。井田内主采煤层为6#煤。煤层倾角平均3°，平均厚度12.0 m。井田地质条件较为简单。 矿井工业储量为9233万t，可采储量为8761万t。矿井设计生产能力为1.2Mt/a。矿井服务年限56.16 a。矿井涌水量不大，正常涌水量为20 m3/h，最大涌水量为30 m3/h。矿井相对瓦斯涌出量为1.08m3/t，属低瓦斯矿井。矿井煤尘无爆炸危险性，但煤层易自燃，自然发火等级为I级。 矿井采用斜井单水平开拓。一矿一面，采煤方法为综合机械化放顶煤开采。全矿采用胶带运输机运煤，辅助运输采用无轨胶轮车。矿井通风方式为中央并列式。 矿井年工作日为330 d，日净提升时间16h，工作制度为“三八制”。 专题部分题目是煤矿开采冒落区注浆充填量预计研究。从冒落区注浆充填这种新的充填开采思路出发，通过研究冒落区顶板活动规律和冒落岩块碎胀系数变化规律，提出冒落区注浆量预计方法，为冒落区充填工程提供依据。 翻译部分主要内容为关于锚杆的分析模型，英文题目为：A
