1、河南理工大學(xué)本科畢業(yè)設(shè)計(jì) 河南理工大學(xué)本科畢業(yè)設(shè)計(jì)xx瓦斯抽采設(shè)計(jì) 瓦斯抽采設(shè)計(jì)摘要：xx開采的二1煤層是突出煤層，為了消除突出危險(xiǎn)進(jìn)行安全生產(chǎn)，對(duì)該井田進(jìn)行瓦斯抽采系統(tǒng)設(shè)計(jì)。確定了xx瓦斯抽采設(shè)計(jì)參數(shù)，根據(jù)瓦斯涌出量、煤層透氣性系數(shù)、鉆孔瓦斯流量衰減系數(shù)等參數(shù)，論證了瓦斯抽采的必要性與可行性。分析了礦井瓦斯涌出源及構(gòu)成，認(rèn)為瓦斯主要來自回采工作面和采空區(qū)，設(shè)計(jì)了瓦斯抽采方法及抽采參數(shù)；計(jì)算了抽采系統(tǒng)抽采量和管路阻力，優(yōu)選抽采系統(tǒng)管路布

2、置；計(jì)算了抽采泵的流量和壓力，并進(jìn)行了瓦斯抽采泵選型；最后制定了打鉆和抽采管理安全技術(shù)措施。關(guān)鍵詞：瓦斯抽采；方案設(shè)計(jì)；設(shè)備選型河南理工大學(xué)本科畢業(yè)設(shè)計(jì) 河南理工大學(xué)本科畢業(yè)設(shè)計(jì)1目 錄第一章 緒論 .............................................................................................................11.1 選題目的
