社会经济建设的发展使得人们对于煤炭能源的需求量也越来越大,煤矿规模随着不断扩大。在煤炭开采过程中,巷道的稳定性对掘进和回采都有着十分重要的影响,但由于地下的地质、水文情况对巷道的影响很大,在地质水文复杂区,尤其是在“三软两高”煤层的巷道掘进中,巷道维护变得十分困难。本文结合淮北矿业集团童亭矿7216工作面的具体情况,通过与传统的“工字钢对子棚”、单一“U型棚”等棚式支护的对比,对锚杆支护技术在“三软两高”煤巷中的应用进行了分析。
The development of socio-economic construction makes people’s demand for coal energy is also increasing, with the continuous expansion of coal mines. In the process of coal mining, the stability of the roadway has a very important impact on the tunneling and mining, but because of the underground geological and hydrological conditions have a great impact on the roadway, in the complex geological and hydrological areas, especially in the High “roadway tunneling, roadway maintenance becomes very difficult. Based on the specific situation of 7216 working face of Tongting Mining Group in Huaibei Mining Group, this paper compared the roof support with the traditional ”I-steel“ and ”U-shaped shed“ The application of protection technology in ”Three soft two high" coal roadway is analyzed.
