安全工程-金河矿通风系统研究论文

本科论文摘 要本文研究的金河煤矿位于盘县西北白果镇小寨村。采矿区是根据采矿许可证确定的。目前的矿场从东到西长约 1.55km，从南到北宽约 1.64km，面积约 1.1444km2。本研究主要用于金河煤矿的通风系统研究。煤层结构简单，稳定性较强。该矿的绝对瓦斯排放为 3.80m3/min，这是一个高瓦斯矿。该区域的煤尘具有爆炸性。矿井通风方式采用中央平行式，通风方式为机械抽排式。本文从理论和实践的角度分析了金河煤矿的各种通风参数，并通过对金河煤矿规模和矿区参数进行了分析，确定了金河煤矿的通风系统。通过计算金河煤矿通风每个工作面的要求，确定每个工作面的空气分布；金河煤矿分两个阶段的通风阻力研究与计算：易通风和难通风；风扇类型和电动机由数据参数确定，例如风扇模型必须产生的风量和风压；概算了矿井通风成本。关键词：矿业通风；煤矿安全；通风系统本科论文AbstractThe Jinhe Coal Mine studied in this paper is located in Xiaozhai Village， Baiguo Town， northwest of Pan County. The mining area is determined according to the mining license. The current mine is about 1.55km long from east to west， 1.64km wide from south to north and 1.1444km2 in area. This research is mainly used for the ventilation system research of Jinhe Coal Mine. The coal seam has simple structure and strong stability. The absolute gas emission of this mine is 3.80m3/min， which is a high gas mine. Coal dust in this area is explosive. The mine ventilation mode adopts central parallel type， and the ventilation mode is mechanical exhaust type.This paper analyzes various ventilation parameters of Jinhe Coal Mine from the perspective of theory and practice， and determines the ventilation system of Jinhe Coal Mine by analyzing the scale and mining area parameters of Jinhe Coal Mine. By calculating the ventilation requirements of each working face in Jinhe Coal Mine， the air distribution of each working face is determined[6]. Research and calculation of ventilation resis...
