Description
技术领域technical field
本发明涉及一种深井支护装置及使用方法,具体是一种具有变形量测功能的深井马头门装置及使用方法。The invention relates to a deep well support device and a use method, in particular to a deep well horse head door device with a deformation measurement function and a use method.
背景技术Background technique
深部矿井呈现出工程地质条件复杂、地压大、巷道维护困难等特点,因而深部巷道围岩稳定性控制成为目前采矿界的重大难题。其中,深立井马头门位处矿井咽喉部位,设计断面大,在施工过程中,围岩反复受到扰动,加之深部围岩流变性显著,因此,深立井马头门破坏失稳的现象时有发生,严重影响围岩稳定性和支护结构安全。Deep mines are characterized by complex engineering geological conditions, high ground pressure, and difficult roadway maintenance. Therefore, the stability control of surrounding rocks in deep roadways has become a major problem in the mining industry. Among them, the Matou gate of the deep shaft is located at the throat of the mine, and the design section is large. During the construction process, the surrounding rock is repeatedly disturbed, and the rheology of the deep surrounding rock is significant. Therefore, the Matou gate of the deep shaft is often damaged and unstable. occur, seriously affecting the stability of surrounding rock and the safety of supporting structures.
为了解决深井马头门围岩稳定性控制的难题,科研人员研发了包括加强支护结构、复合支护结构及联合支护结构等的各种支护结构及装置。但是,现有的支护装置仍然存在诸多局限性。其一,支护结构所提供的支护强度不足、刚度偏小、适应围岩变形的能力差;其二,围岩变形量测须配备复杂、价格昂贵的监测系统,支护结构本身无简单测量装置;其三,支护结构施工工艺复杂,需要进行一次支护、二次支护,甚至是三次及更多次支护,巷道维护效率低、造价高;其四,支护体、支护构件的可回收性低。由此可见,目前的深部矿井马头门支护结构在安全性、有效性、经济性等方面均存在较大的缺陷,严重影响了矿井运输提升作业,妨碍了本质安全型、高效绿色矿井的建设进程,也成为当前建设大型现代化矿井的制约因素之一。因此,在深部矿井马头门围岩支护的现场实施过程中急需一种既能保证巷道稳定、安全,又能高效、经济地维护巷道的支护装置。In order to solve the problem of stability control of the Matoumen surrounding rock in the deep well, researchers have developed various support structures and devices including reinforced support structures, composite support structures and combined support structures. However, the existing supporting devices still have many limitations. First, the supporting structure provided by the supporting structure is insufficient in strength, low in stiffness, and poor in adapting to surrounding rock deformation; second, the measurement of surrounding rock deformation must be equipped with a complex and expensive monitoring system, and the supporting structure itself is not simple. measuring device; thirdly, the construction process of the support structure is complicated, and it is necessary to carry out primary support, secondary support, or even three or more times of support, and the roadway maintenance efficiency is low and the cost is high; fourthly, the support body, support The recyclability of the protective elements is low. It can be seen that the current deep mine horse head gate support structure has relatively large defects in terms of safety, effectiveness, and economy, which seriously affects the mine transportation and lifting operations, and hinders the development of intrinsically safe and efficient green mines. The construction process has also become one of the restrictive factors for the current construction of large modern mines. Therefore, there is an urgent need for a support device that can not only ensure the stability and safety of the roadway, but also efficiently and economically maintain the roadway during the field implementation of the Matoumen surrounding rock support in deep mines.

The present invention configures a two-way digital display ruler on the top beam, and the two-way digital display ruler adopts a digital display screen to display the change of the extension distance of the upper tape and the extension distance of the lower tape. The I-beam on the outer layer of the top beam with a buckle on the ruler belt. When the rock mass exerts confining pressure on the top beam, the top beam will deform to a certain extent, so that the extension distance of the upper ruler belt will change, and then it can be measured through the digital display screen. The vertical deformation of the I-beam outer layer of the top beam after the top rock mass exerts confining pressure on the top beam. Since the lower tape of the two-way digital display ruler is hooked on the iron wire, the two ends of the iron wire are straightened and fixed by embedded steel nails In the shoulder sockets on both sides of the rock mass, when the rock mass exerts confining pressure from both sides, the two sides of the rock mass press against the Matoumen. The iron wire will be deformed, and then the change of the extension distance of the lower tape can be obtained through the digital display screen, so as to provide basic data for predicting the disaster risk of the roof;
3、本发明为模块化结构装置,组装方法简单,施工效率较高,并且无需大型专门的变形测量系统,造价低、工程上更实用、经济;3. The present invention is a modular structure device, the assembly method is simple, the construction efficiency is high, and there is no need for a large-scale special deformation measurement system, the cost is low, and the engineering is more practical and economical;
4、本发明具有资源节约、材料回收重复利用的优点,一旦巷道破坏或废弃的时候,可以将原来施工好的支架依据模块的组装方式进行解体回收利用;对于破坏较大的模块或部件进行一定的维修、替换后仍能继续使用,节约了支护材料,节省了巷道维护成本,具有显著的经济效益。4. The present invention has the advantages of resource saving and material recycling and reuse. Once the roadway is damaged or discarded, the originally constructed support can be disassembled and recycled according to the assembly method of the modules; It can still be used after maintenance and replacement, saves support materials, saves roadway maintenance costs, and has significant economic benefits.
