摘要
本設(shè)計(jì)是對寸草塔礦的初步設(shè)計(jì)所給定基本條件進(jìn)行的礦井排水系統(tǒng)及排水設(shè)備選型設(shè)計(jì)。通過技術(shù)和經(jīng)濟(jì)性比較確定了礦井排水系統(tǒng)形式，進(jìn)行了礦井排水設(shè)備選型設(shè)計(jì)計(jì)算，確定選用所選的離心式水泵。然后根據(jù)寸草塔礦井下涌水情況、井底車場布置情況，選擇水泵、管路及管路附件等設(shè)備的類型和具體型號(hào)。進(jìn)行管路布置、計(jì)算管路阻力損失、確定管路特性方程、確定水泵工況點(diǎn)。在進(jìn)行排水設(shè)備選型計(jì)算的時(shí)候，通過分析原始資料，選取了可能適合礦井的不同水泵。通過對不同型號(hào)水泵工況點(diǎn)的計(jì)算比較，通過對經(jīng)濟(jì)流速、排水時(shí)間和吸水高度等的校驗(yàn)，排除不合適的水泵，選取一個(gè)相對來說符合要求的水泵以及管路。再根據(jù)水泵工況點(diǎn)參數(shù)，計(jì)算所需功率，選擇配用電動(dòng)機(jī)，計(jì)算經(jīng)濟(jì)指標(biāo)費(fèi)用。然后對對所選水泵進(jìn)行介紹。最后設(shè)計(jì)水泵房、水倉，確定其各項(xiàng)基本參數(shù)，繪制水泵房布置圖。

Abstract
This design is the basic conditions for the preliminary design of the basic conditions for the design of the coal mine drainage system and the drainage equipment selection design. Through the comparison of technology and economy, the mine drainage system is determined, and the selection of mine drainage equipment is calculated.. Then according to the inch grass tower mine gushing water, bottom yard layout situation, select pumps, piping and pipe accessories equipment types and specific models. The pipeline layout, calculation of the pipeline resistance loss, determine the pipeline characteristics, determine the pump point. In the drainage equipment selection calculation, through the analysis of the original data, select the mine may be suitable for different pumps. Through the calculation of different types of pump operating point compared through the economic flow velocity and duration of drainage and imbibition height check, exclude the inappropriate pump, select a relatively conform to the requirements of pumps and piping. According to the pump operating point parameters, calculate the required power, select the motor, the calculation of the economic index cost. And then introduce the selected pump.. Finally, the design of the pump room, water warehouse, determine its basic parameters, drawing the layout of the pump room.
