随着煤炭资源开采深度的不断增大，瓦斯灾害事故日益频发，严重影响煤矿安全高效开采，对矿井经济效益及社会形象造成深远的影响。倾斜煤层的瓦斯精准抽采是一个技术难题，在开采此类煤层时应先解决开采前后的瓦斯涌出问题，因而进行倾斜煤层的瓦斯涌出量预测显得尤为重要。国内外科研工作者也在此方面开展了大量矿井瓦斯涌出预测、瓦斯抽采技术的研究，取得了明显的效果。但如何就硫磺沟煤矿倾斜煤层形成一套有针对性的矿井瓦斯抽采技术体系，对确保硫磺沟煤矿工作面安全高效回采方面具有十分重要的意义。

针对硫磺沟煤矿（4-5）06综放工作面倾斜煤层埋深大、瓦斯含量高等特点，通过对矿井地质和工作面情况进行调研分析，获得（4-5）06工作面煤层和瓦斯赋存特征，通过测量采集煤样的瓦斯基础参数，更详尽地得到（4-5）06工作面煤层瓦斯赋存规律，在此基础上，利用瓦斯涌出量关键因素分析动态预测系统对（4-5）06综放工作面回采过程中的瓦斯构成及涌出量进行预测，并结合灰色理论与现场实时观测瓦斯涌出规律，分析得到瓦斯涌出规律与各影响因素之间的关系，由此制定了相应的瓦斯抽采措施；基于数值模拟及现场监测的方法得到（4-5）06综放工作面覆岩“三带”高度，并在此基础上进行高位钻场的设计。通过对以上瓦斯抽采措施应用总结，构建出一套适用于硫磺沟煤矿综放回采工作面的瓦斯抽采治理技术体系，然后应用于现场实践，指导工作面进行瓦斯抽采工作。

根据实时监测该技术系统应用过程的效果，对采集到的数据进行分析。利用行业规程中的指标对技术体系实施效果进行检验，获得了较好的效果，保证硫磺沟煤矿综放回采工作面的安全高效开采。有效治理瓦斯灾害，对高瓦斯矿井安全生产意义重大。

With the continuous increase in the mining depth of coal resources, gas disaster accidents have become more frequent, which seriously affects the safe and efficient mining of coal mines, and has a profound impact on the economic benefits and social image of the mine. Accurate gas drainage of inclined coal seams is a technical problem. When mining such coal seams, the gas problem before and after mining should be solved first. Therefore, it is particularly important to predict the amount of gas emission from inclined coal seams. Researchers at home and abroad have also carried out a large number of studies on mine gas emission prediction and gas drainage technology in this regard, and have achieved significant results. However, how to form a targeted mine gas drainage technology system for the inclined coal seams of the Liuhuanggou Coal Mine is of great significance for ensuring the safe and efficient mining of the working face of the Liuhuanggou Coal Mine.

For LiuHuangGou (4-5) 06 fully-mechanized caving coal mine coal seam buried depth, high gas content, etc, through research analysis of mine geological and mining conditions, obtain (4-5) 06 working face of coal seam and gas occurrence characteristics, basis of coal sample was taken by measuring the gas parameters, more detail get (4-5) 06 working face of coal seam gas occurrence regularity, on this basis, the use of critical gas emission factor analysis dynamic prediction system (4-5) 06 full-mechanized caving mining face in the process of the gas composition and volume of forecast, and combining the gray theory and the real time observation gas emission law, analysis law of gas emission and the relationship between various influencing factors, thus formulated the corresponding gas extraction; Based on the method of numerical simulation and field monitoring, the "three belts" height of overlaying rock in (4-5) 06 fully mechanized caving face was obtained, and the design of high drilling field was carried out on this basis. Through the application and summary of the above gas extraction measures, a set of gas extraction control technology system suitable for fully mechanized caving mining face in Sulfagou coal mine is constructed, and then applied in field practice to guide the gas extraction work in working face.

According to the effect of real-time monitoring of the application process of the technology system, the collected data are analyzed. The implementation effect of the technical system is tested by using the indexes in the industry regulations, and a good effect is obtained to ensure the safe and efficient mining of the fully mechanized caving face in Susulagou coal mine. Effective control of gas disaster is of great significance to the safety production of high gas mines and plays an important role in promoting the further improvement of national coal mine safety situation.
