摘 要:进行煤矿深部开采时,周围环境较为复杂,地应力、地温以及渗透压都比较高,同时还会受到强烈的开采扰动影响,因此深部的巷道环境十分复杂,经常伴随着支护体失效、巷道破坏、顶板下沉以及底鼓等问题的产生,同时还会加重水、瓦斯、高温以及冲击地压等灾害的发生,严重影响了煤炭的安全开采。因此,为了减少深部开采时巷道围岩的变形量,保证通风和运输的安全,需要选择合适的支护技术。In the deep mining of coal mine, the surrounding environment is more complex, the ground stress, ground temperature and osmotic pressure are relatively high, and it will also be affected by the strong mining disturbance. Therefore, the tunnel environment in the deep part is very complicated. It is often accompanied by problems such as failure of support body, damage of roadway, sinking of roof, and bottom drum. At the same time, it will also aggravate the occurrence of disasters such as water, gas, high temperature and impact ground pressure, which has seriously affected the safe mining of coal. Therefore, in order to reduce the deformation of roadway surrounding rock during deep mining and ensure the safety of ventilation and transportation, it is necessary to choose a suitable support technology.
