一种巷道顶板锚杆钻孔充填树脂药卷的方法 Method for drilling resin bottle in roof roadway anchor hole drilling
技术领域 Technical field
本发明涉及一种充填树脂药卷的方法， 尤其是一种适用于巷道顶板岩层较破碎以及 巷道高度在 3.0 m以上的巷道顶板锚杆钻孔充填树脂药卷方法。 The invention relates to a method for filling a resin powder roll, in particular to a method for filling a resin roll of a roadway roof bolt for a roadway roof with a relatively broken rock formation and a roadway height of 3.0 m or more.
背景技术 Background technique
我国煤矿于 1956年开始在岩巷中使用锚杆支护， 至今已有 50多年的历史。 锚杆支 护技术经历了从低强度、 高强度到高预应力、 强力支护的发展过程。 我国煤矿锚杆支护 首先在岩巷中应用成功， 并在岩巷中大力推广应用了以 "三小"为代表的锚喷支护技术。 20世纪 60年代锚杆支护开始应用于采区巷道。由于煤层巷道围岩相对比较松软破碎，又 受到采动影响， 巷道围岩变形大， 对支护技术要求高。 我国早期采用的锚杆支护强度、 刚度低， 支护原理上仍属于被动支护， 加之锚杆支护理论、 设计方法、 支护材料、 施工 机具、 监测仪器等还不成熟， 导致煤巷锚杆支护技术发展缓慢。 1990年， 我国国有重点 煤矿煤巷锚杆支护仅占 3 %〜5 %， 煤巷支护主要以棚式支护为主。 China's coal mines began to use bolt support in rock roads in 1956, and it has been more than 50 years old. Bolt support technology has evolved from low strength, high strength to high prestress and strong support. China's coal mine bolt support was first applied successfully in the rock roadway, and the anchor spray support technology represented by "three small" was vigorously promoted and applied in the rock roadway. In the 1960s, bolt support began to be applied to mining roadways. Because the surrounding rock of the coal roadway is relatively soft and broken, and affected by mining, the surrounding rock of the roadway has large deformation and high requirements for supporting technology. The bolt support strength and rigidity adopted in China in the early stage are still passive support. The bolt support theory, design method, supporting materials, construction equipment, monitoring instruments, etc. are still immature, leading to coal lanes. Bolt support technology has developed slowly. In 1990, China's state-owned key coal mine roadway bolt support only accounted for 3% to 5%, and coal road support was mainly shed-type support.
在 "九五"期间， 原煤炭部把煤巷锚杆支护技术列为重点课题， 展开了更深入、 细 致和全面的研究试验工作。 特别是 1996-1997年我国引进了澳大利亚锚杆支护技术， 在 邢台矿务局进行了现场演示。 同时经过科研院所、 大专院校和煤炭企业的联合攻关， 使 我国煤巷锚杆支护技术有很大提高。 高强度螺纹钢锚杆并进行加长或全长树脂锚固， 动 态支护设计方法， 小孔径树脂锚固预应力锚索等新技术、 新材料、 新方法得到广泛认可， 应用于煤顶巷道、 复合与破碎顶板巷道等困难条件， 取得良好的支护效果和技术经济效 、 During the "Ninth Five-Year Plan" period, the former Ministry of Coal listed the coal road bolt support technology as a key issue, and carried out more in-depth, detailed and comprehensive research and test work. In particular, in 1996-1997, China introduced the Australian bolt support technology and conducted a live demonstration at the Xingtai Mining Bureau. At the same time, through the joint research of research institutes, universities and coal enterprises, the bolt support technology of coal roadways in China has been greatly improved. High-strength rebar anchors are extended or full-length resin anchoring, dynamic support design methods, small-aperture resin anchored prestressed anchor cables and other new technologies, new materials and new methods are widely recognized, applied to coal roof roadway, composite and Difficult conditions such as broken roof roadway, good support effect and technical and economic efficiency,

进入 21世纪以来， 随着综采放顶煤、 厚煤层一次采全高开采技术的快速发展和大面 积应用， 对煤巷锚杆支护技术提出更高的要求。 综采放顶煤和一次采全高工作面一般要 求回采巷道沿煤层底板布置， 巷道顶板为比较破碎的煤层， 有时甚至是全煤巷道。 此外， 随着煤矿开采强度与产量的大幅度提高， 要求的巷道断面越来越大。 为了减少煤炭损失， 沿空掘巷应用得越来越广。 所有这些都使巷道支护难度显著增加。 为此， 充州、 潞安、 晋城、 西山、 淮南、 淮北、 新汶、 龙口、 开滦、 铁法、 徐州、 华亭等矿区相继开展了本 矿区煤巷锚杆支护成套技术的研究、 试验与推广应用。 锚杆支护在大断面巷道、 煤顶和 全煤巷道、 沿空掘巷、 松软破碎围岩巷道等困难条件得到成功应用， 显著提高了巷道支 护效果， 降低了支护成本， 为采煤工作面的快速推进， 矿井实现高产高效创造了良好的 条件。
近年来， 为了解决深部高地应力巷道、 特大断面巷道、 受强烈采动影响巷道、 沿空 留巷等复杂困难条件支护难题， 我国又开发出高预应力、 强力锚杆与锚索支护技术， 真 正实现了锚杆的主动、 及时支护， 充分发挥了锚杆的支护作用。 井下应用大幅度减少了 巷道围岩变形与破坏， 巷道支护与安全状况发生了本质改变。 同时， 实现了高强度、 高 刚度、 高可靠性与低支护密度的 "三高一低" 的现代锚杆支护设计理念， 在保证支护效 果的前提下， 显著提高了巷道掘进速度与工效。 Since the beginning of the 21st century, with the rapid development and large-area application of fully mechanized mining technology for fully mechanized top coal caving and thick coal seams, higher requirements have been put forward for bolting technology of coal roadway. Fully mechanized top coal caving and full mining high working face generally require the mining roadway to be arranged along the coal seam floor. The roof of the roadway is relatively broken coal seam, and sometimes even the whole coal roadway. In addition, with the substantial increase in the intensity and output of coal mining, the required roadway section is getting larger and larger. In order to reduce coal losses, the application of roadway along the air is becoming more and more widespread. All of this makes the roadway support significantly more difficult. To this end, Chongzhou, Chun'an, Jincheng, Xishan, Huainan, Huaibei, Xinwen, Longkou, Kailuan, Tiefa, Xuzhou, Huating and other mining areas have successively carried out research and experiments on the complete set of bolting technology for coal roadway in this mine area. And promote the application. The bolt support has been successfully applied in difficult conditions such as large section roadway, coal roof and full coal roadway, along the goaf, and soft broken surrounding rock roadway, which significantly improved the roadway support effect and reduced the support cost. The rapid advancement of the working face has created favorable conditions for the mine to achieve high productivity and high efficiency. In recent years, in order to solve the difficult problems of deep high-stress roadway, extra-large section roadway, roadway affected by strong mining, and retaining roadway along the air, China has developed high prestressed, strong bolt and anchor support technology. The real and timely support of the bolt is realized, and the support of the bolt is fully exerted. Downhole application has greatly reduced the deformation and damage of the surrounding rock of the roadway, and the roadway support and safety conditions have undergone substantial changes. At the same time, the design concept of "three high and one low" modern bolt support with high strength, high rigidity, high reliability and low support density is realized. Under the premise of ensuring the support effect, the tunneling speed is significantly improved. Work efficiency.
经过多年的研究与实践， 到目前为止， 可以说我国煤矿已经形成了有中国特色的煤 巷锚杆支护成套技术体系， 锚杆支护已经成为煤矿巷道首选的、 安全高效的主要支护方 式。 但是， 由于在开挖巷道时， 顶板岩层中形成破碎带， 顶板纵向裂隙发育较充分， 导 致在打顶板锚杆钻孔时经常在孔壁周围出现小范围空洞， 这使得在充填树脂药卷时很难 将其顺利填充至钻孔底部； 而且在一些巷道中， 有时会遇到先铺金属网后打锚杆的情况， 工人在充填顶板锚杆树脂药卷时由于金属网的阻隔难以将药卷填充至钻孔深部； 再者， 有些矿井的巷道断面垂向距离较大， 工人在充填顶板锚杆药卷时， 需要借助高脚架等辅 助工具， 同时需要几个工人相互配合才能完成填充任务， 这样便降低了工作效率， 影响 巷道推进速度。 以上问题都严重违背了巷道安全高效施工的初衷。 After years of research and practice, it can be said that China's coal mines have formed a complete set of technical systems for coal roadway bolt support with Chinese characteristics. Bolt support has become the preferred, safe and efficient main support method for coal mine roadways. . However, since the fracture zone is formed in the roof rock formation when the roadway is excavated, the longitudinal crack of the roof plate is fully developed, which results in a small-scale cavity around the hole wall when drilling the roofing bolt, which makes the filling of the resin film. It is difficult to fill it smoothly to the bottom of the borehole; and in some roadways, sometimes it is encountered that the anchoring rod is laid after the metal mesh is first laid, and the worker is difficult to take the medicine due to the barrier of the metal mesh when filling the resin coil of the roof anchor rod. The roll is filled deep into the borehole; in addition, some mines have a large vertical distance in the roadway section. Workers need to use auxiliary tools such as a scaffold when filling the roof bolts, and several workers need to work together to complete the filling. Tasks, which reduce work efficiency and affect the speed of roadway propulsion. The above problems are seriously contrary to the original intention of safe and efficient construction of roadways.
