本科论文（设计）夹河煤矿1.5 Mt-a新井设计-煤矿软岩巷道锚网索耦合支护技术研究.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。 一般部分是夹河煤矿1.5 Mt/a新井设计。全篇共分为十个部分：矿区概况与井田地质特征、井田境界和储量、矿井工作制度和设计生产能力及服务年限、井田开拓、准备方式―采区巷道布置、采煤方法、井下运输、矿井提升、矿井通风及安全和矿井基本技术经济指标。 夹河煤矿位于江苏省徐州市，矿井总面积约为13.3 km2，井田走向长平均约4.1 km，倾向长平均约3.2 km。本设计主采煤层为7#、9#煤，平均厚度为3.3 m、3.1 m，煤层赋存稳定，为缓倾斜煤层，倾角5°～29°，平均17°。井田内工业储量为170.64 Mt，可采储量为120.51 Mt。矿井正常涌水量120 m3/h，最大涌水量230 m3/h；矿井绝对瓦斯涌出量为10.02 m3/min，属于低瓦斯矿井，不易自燃，煤尘有爆炸危险。 夹河矿设计年生产能力为1.5 Mt/a，服务年限为61.8年。矿井开拓方式为立井两水平加暗斜井延深，开拓水平分别设置在-550 m和-850 m。 设计首采区采用集中上山准备方式，工作面长度230 m，采用走向长壁综合机械化采煤方法，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。 专题是煤矿软岩巷道锚网索耦合支护技术研究。 翻译部分是无煤柱沿空留巷围岩的稳定性及变形，英文原文题目是“Stability and deformation of surrounding rock in pillarless gob-side entry retaining”。 关键词：立井；暗斜井；采区；综采；中央并列式；软岩；沿空留巷 ABSTRACT This design consists of three parts: the general part, the special part and the translated part. The general design is about a 1.5 Mt/a new underground mine design of Jiahe coal mine. It has ten chapters: an outline of the mine and mine field geology; boundary and reserves; productive capacity, service life and working system of mine; development engineering of coalfield; the layout of mining area; the method used in coal mining; transportation of underground; mine lifting; mine ventilation and safety; the economic and technologic index of the mine. The Jiahe mine field lies in the Xuzhou city of Jiangsu province, the total area of the mine is 13.3 km2. It’s about 4.1 km on the strike and 3.2 km on the dip. There is two minable coal seam: No.7 and No.9, and the average thickness of the seam is 3.3 m and 3.1 m. They are stable and fluty inclined. The dip angle is from 5 degree to 29 degree, and is 17 degree on average. The normal flow of the mine is 120m3/h, and the maximum mine flow is 230 m3/h. The absolute gas emission rate of mine is 10.02 m3/min which belongs to low gas mine. The seams don’t have self-combustion tendency, and the coal dust has explosion hazard. The productive capacity of Jiahe mine is 1.5 million tons per year, and it
