煤炭工业是宁夏国民经济发展中的支柱产业之一。汝箕沟煤矿开采历史久远，自1960年开始建设西沟平硐之后，经过多次改扩建而发展成为现在的一个中型矿井。由于多种因素，目前矿井开拓系统、通风系统比较分散，掘、抽、采各生产环节之间矛盾非常紧张。这些矛盾严重制约着建设高产高效现代化矿井的步伐，也给矿井安全生产和经营管理带来严重困难。因此系统研究矿井安全系统技术改造问题，对汝箕沟煤矿实现安全高效生产具有重要意义。 论文采用综合分析和现场试验相结合的研究方法，以合理开采利用汝箕沟煤矿的优质太西煤资源为出发点，以提高矿井抵御各种灾害的能力、增加矿井经济效益为目的，在充分分析制约矿井长远发展的关键安全技术问题的基础上，对汝箕沟煤矿的安全系统的技术改造问题进行了比较深入的研究，提出了矿井主要巷道系统技术改造和矿井通风系统技术改造的方案，以及相应的瓦斯防治技术、火灾防治技术方案。这为具有煤与瓦斯突出及小窑火害威胁严重的汝箕沟煤矿的矿井技术改造提供了科学依据。提出的技术改造方案已经得到实际应用，并已取得了良好的安全技术和经济效果。

With the rapid development of China's economy, as China's provinces and regions rich in coal one of the Ningxia Hui Autonomous Region, Ningxia Coal Industry is in the mainstream of national economic development. Ningxia in recent years due to invested in these projects and ensure that the greatly increased the demand for coal. In order to improve the efficiency of production and mine production safety nature of the ventilation systems are necessary to optimize the transformation to ensure that the premise of mine safety, mine subsequent technological transformation, and to ensure that mine long-term healthy development. Rujigou coal mine currently developing systems, ventilation systems more decentralized, excavation, pumping, and mining production processes all the contradictions between the growing tension, these contradictions serious constraints on the construction of high yield and high efficiency of modern mine, but also to mine safety, production, and management brought about many difficulties. Papers from the safe, effective, rational exploitation and use of "too Western" coal as the fundamental starting point to enhance mine to withstand all kinds of natural disasters, increase the economic benefits of the mine as the greatest purpose of the mine fire area surrounding small pits, small kiln, the gas situation, taking full account of the ventilation system, from top to bottom coal convergence subsequent mining, mining methods, mining pressure, ventilation, gas control, fire prevention, water control, anti-mine long-term process, such as constraints on the basis of development issues , Rujigou mine is the technological transformation of research, high yield and high efficiency to achieve the purpose of At the same time, mining safety can be achieved. This coal and gas outburst small kiln fire damage and serious hidden dangers of the technological transformation of the mine provided a basis.
