店考煤矿通风设计-毕业论文.doc

摘 要 安全项目的设计建设始终是煤矿生产中非常重要的一部分，它不仅关系到煤矿生产人员的人身安全，更与煤矿生产的总工程密不可分。本设计根据店考煤矿的各项实际指标参数以及现有的安全生产技术水平，对店考煤矿做了全面的安全生产设计。设计除对煤矿进行基本设计以外，还就该煤矿的灾害进行大体分析，并重点就瓦斯灾害防治作出具体设计。按照店考煤矿的开拓方式和地质构造，选用合理的通风系统，对综采掘进工作面以及硐室通风，井下通风设施和构筑物等内容进行具体设计。 店考煤矿/a为新矿井通风设计，该矿设计可采储量为万吨,服务年限为a。设计采用的联合开拓方式，划分个采区。 矿井通风方式中央并列，抽出式通风方法，采煤工作面采用型通风上行，掘进工作面采用式通风矿井容易时期设计需风量为m3/s，困难时期设计需风量为6m3/s，相对应的选择矿用防爆轴流式通风机2K电动机，且对矿井所需通风构筑物进行。关键词Abstract Design and construction of the security project?is a very important part in the production of coal mine production,?it is not only related to the?coal mine production staffs’ personal safety,?but also is inseparable to the?total project?of mine production. This design according to?the actual?parameters and the existing-technical level of safety in production?of? Diankao coal mine,?design comprehensive safety production?of this coal mine.?This design?in addition to?the basic design of?the coal mine generally?analysis?mine?disaster,?and focus on the?prevention and control of gas disaster make specific design. According to the?development method and?geological structure?of Diankao coal mine, it choose reasonable ventilation system and make the specific design for fully mechanized?heading face,?chamber ventilation, underground ventilation?facilities and?structures. Diankao?coal mine annual output is?1.20Mt/a, this design is make for the new?mine?ventilation, and its’ coal recoverable reserves istons. This coal use?the?main diagonal?auxiliary vertical alliance?development,?and divided into three mining area. ? The mine ventilation?of Diankao coal mine choose?the central parallel ventilation system and exhaust ventilation draft type, Coal mining face use?V?type ventilation. The tunneling working surface use blowing ventilation. Mine?easily?during the design?required air volume?is 61m3/s,?during mine?difficult?design?required air volume?is 66m3/s,select the?corresponding?explosion-proof?axial?flow ventilator?two 2K60?and?power 160Kw?Y-315L1-2 motor?a,?and?on mine?vent
