Argillaceous roadway anchoring drilling equipment and roadway anchoring method

Abstract

The invention discloses argillaceous roadway anchoring drilling equipment and a roadway anchoring method, and relates to the technical field of argillaceous roadway anchoring. The equipment comprises a drilling machine, high-polymer non-polar punching liquid and a punching liquid recycling device, the punching liquid recycling device comprises a liquid collecting device, a filtering device and a pressurizing device; the liquid collecting device comprises an orifice shade, a mixed slurry guide pipe and a liquid collecting box; the filtering device comprises a filtering sieve and a punching liquid box; and the pressurizing device comprises a pressurizing pump used for pumping the punching liquid in the punching liquid box to the drilling machine. The high-polymer non-polar material is adopted as the punching liquid in an anchoring technology, and the weakening effect of the factor of water on argillaceous surrounding rock in the drilling process is avoided; and the punching liquid not only plays a role in flushing out broken rock debris in the drilling construction process, but also can intrude into a certain range of the interior of a hole wall to form a non-polar protection layer, thereby resisting invasion weakening of a water source to an anchoring structure, improving the hydrophobicity of the argillaceous surrounding rock, and meanwhile, being beneficial to guaranteeing long-term stability of the anchoring structure of the argillaceous surrounding rock.

Description

technical field [0001] The invention relates to the technical field of mud roadway anchoring, in particular to a mud roadway anchoring drilling device and a roadway anchoring method. Background technique [0002] The argillaceous weakly cemented rock mass is widely distributed in various mining areas in my country, and the stability of the argillaceous weakly cemented rock mass is significantly affected by the factor of water. The wide application of bolt (cable) support technology has greatly improved the stability of related underground projects, but in the environment where muddy weakly cemented rock mass exists, the anchorage effect of the bolt (cable) support system is not good. , is prone to failure.

Problems solved by technology

The wide application of bolt (cable) support technology has greatly improved the stability of related underground projects, but in the environment where muddy weakly cemented rock mass exists, the anchorage effect of the bolt (cable) support system is not good. , highly prone to failure

This is mainly because the existence and use of water is inevitable no matter in the natural geological environment or in the current construction process. After the contact and interaction between water and muddy weakly cemented rock mass, it will lead to problems such as muddying and weakening, which is extremely difficult. greatly affect the stability of the surrounding rock

In the traditional bolt (cable) construction technology, water is often used as punching fluid during the drilling process, resulting in direct contact between water and weakly cemented rock mass, which disturbs the stable state of weakly cemented rock mass in a dry environment. , Loose borehole walls affect the construction quality of the anchor rod (cable), and with the time effect, affect the stability of the anchoring unit, thereby endangering the entire anchoring structure, seriously affecting the quality of the project, and greatly affecting the safety of personnel. Hidden danger

[0003] In addition, due to the poor anchoring effect of the mud roadway, other supporting components such as pillars, steel beams, and steel belts need to be added for control, which not only increases the construction period, but also increases the cost input, consuming time, manpower and material resources
