孙村矿1.8Mta新井初步设计-承压水与安全开采的技术与施工-煤与瓦斯突出灰色-神经网络预测模型的建立研究.docx

摘 要本设计包括三个部分：一般部分、专题部分和翻译部分。一般部分为孙村矿1.8Mt/a新井初步设计，共分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、设计生产能力及服务年限；4.井田开拓；5.准备方式—采区巷道布置；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。孙村煤矿位于山东省泰山东侧的新泰市新汶办事处孙村镇境内，地处新汶煤田东部，位居山东新汶矿业集团公司腹地。东与张庄煤矿，西与良庄煤矿相邻，南依蒙山山系，北与莲花山相望，柴汶河自东向西流经井田之上。东北距新泰市9km，西距磁窑68km，西北距济南168km。孙村井田位于莲花山和蒙山山脉两大分水岭之间，地面为平缓的丘陵地带，地面标高在+165～+210m之间。井田西部地形较平坦，东部起伏较大。总的趋势是西北部地形较低，东南部较高。煤系地层大部为冲积层所掩盖，只有溪沟中略有出露。奥陶系石灰岩广泛出露于井田南部区域。井田中南部有柴汶河纵贯东西。工业场地建在柴汶河南岸的小平原之上，该工业场地内主斜井井口标高为+175.5m。20世纪90年代围绕千米北立井建设的北立井工业场地位于柴汶河北岸，井口标高为199.5m。在井田内可采煤层中，2#煤层平均厚度3.5m，是井田内的首采煤层和主采煤层。4#煤层是主采煤层，平均厚度2.8m。该煤层赋存稳定，结构简单，全井田范围内均可采。矿井最大相对瓦斯涌出量为5m3/t，属于低瓦斯矿井。煤尘具有一定的爆炸性和自然发火危险性。矿井采用斜井多水平上山开拓，采用采区式和中央并列式混合通风。一矿一面，采煤方法为长壁综采一次采全高开采。煤炭运输采用胶带输送机，辅助运输采用蓄电池电机车牵引矿车。矿井年工作日为330 d，每天净提升时间16 h。矿井工作制度为“三八”制。专题部分题目是承压水与安全开采的技术与施工。翻译部分是一篇关于煤与瓦斯突出灰色-神经网络预测模型的建立研究的论文，英文原文题目为：Establishment of grey-neural network forecasting model of coal and gas outburst。关键词：斜井；采区；综采；千米立井AbstractThis design includes three parts: the general part, the special subject part and translation part.The general part is a new preliminary design of Suncun wells that annual output is 1.8Mt. The design includes ten chapters: 1. Mine overview and mine field geological features; 2. The mine field boundary and the reserves; 3. Mine system of work, design production capacity and service life; 4. Mine field extension; 5. Preparation-with the district roadway layout; 6. Mining methods; 7. Underground transport; 8. Mine hoist; 9. Mine ventilation and safety technology; 10. Mine basic technical and economic indicators.Suncun coal mine is located in the territory of the Suncun town of Taishan in Shandong Province, east side of the Xintai City Xinwen office, located in the eastern part of the Xinwen coal field, The hinterland of the Shandong Xinwen Mining Group Company.In the east side, it is adjacent to Zhangzhuang coal mine, in the west side, it is adjacent to Liangzhuang coal mine, Mengshan mountain in the south side of the attachment, The north side with
