采用injecto-patin喷枪浇灌杆柱的方法,需要把一定长度的杆柱插入炮孔内,然后,用水泥砂浆把它完全浇灌起来。浇灌完了之后,整个炮孔周围的岩层就和杆柱胶结在一起,形成一个连续的整体;并且增加了杆柱本身的初始强度。结果保证了在垂直方向大大加固,使横向移动具有较大的阻力。在开采过程中重新建立应力的平衡,由于应力的重新分布,阻止了岩层的破碎,避免了岩层间的分离;使顶板沉降减小到最低限度。比起目前通用的杆柱技术,其更重要的优点是灌浆过程,大大有助于防止杆柱的锈蚀,这样就延长了它们的使用寿 The use of injecto-patin spray gun rod method, the need to insert a certain length of the column into the hole, and then, with cement mortar it completely irrigated. After watering is finished, the rock formation around the entire bore hole is cemented with the post to form a continuous mass; and the initial strength of the post itself is increased. As a result, it is greatly reinforced in the vertical direction, so that the lateral movement has greater resistance. In the mining process to re-establish the balance of stress, due to the redistribution of stress, to prevent the rock crushing, to avoid the separation between rock layers; roof settlement reduced to a minimum. A more important advantage of the current pillar technology is the grouting process, which greatly helps to prevent the corrosion of the pole, thus lengthening their service life
