丁集煤矿1.5Mt/a新井初步设计 摘要 本设计包括三个部分：一般部分、专题部分和翻译部分。 一般部分为丁集煤矿1.5 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。 丁集矿井位于安徽省淮南市西北部，距淮南市洞山约50km，行政区划隶属淮南市潘集区和凤台县境内。井田形状近似长方形，东西长约9.0 km，南北宽约8.0 km，面积约47.22 km2。井田内主采煤层为一层，为11-2#煤。煤层倾角平均7°，平均厚度3.5m。井田地质条件较为简单。 矿井工业储量为215.58Mt，可采储量为122.05Mt。矿井设计生产能力为1.5Mt/a。矿井服务年限62.6 a。矿井涌水量不大，正常涌水量为480 m3/h，最大涌水量为600 m3/h。矿井相对瓦斯涌出量为5.98 m3/t，属低瓦斯矿井。 矿井采用立井单水平开拓，采煤方法为倾斜长壁全部跨落一次采全高。全矿采用胶带运输机运煤，辅助运输采用矿车。矿井通风方式前期为中央并列式，后期根据需要在井田北翼增加一个区域风井。 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。 翻译部分是一篇关于神经网络程序在采矿工业中应用的，英文题目为Practical Neural Network Applicatio
