Problems solved by technology
[0003] Nowadays, the laying of bundled pipes is a purely physical project with cumbersome procedures and high labor intensity. Construction personnel must carry out protection of steel pipes, carry bundled pipes, and connect protection in a small space under and behind the hydraulic support near the goaf. Steel pipe and other processes work in a narrow space, and the operators cannot stand. Not only is the work efficiency low, but also the installation site is close to the goaf, and there are many large pieces of falling coal and rocks, which slows down the movement speed of the operators under the hydraulic support. , which increases the working time and also increases the danger
[0004] From the above analysis, it can be seen that the current method of laying pipe bundles has too many disadvantages, so it is necessary to propose a new method of laying and installing bundle pipes to improve the current disadvantages

Embodiment Construction
[0026] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0027] Such as figure 1 , the bundle pipe 6 of the fully mechanized caving face of the present invention is installed in the goaf 4, and the bundle pipe 6 and the protective steel pipe 5 are transported and installed in the working space 2. The working space 2 is located below the swing tail boom 11 of the hydraulic support 1, and the swing tail boom 11 is used to support the coal and rocks that have fallen from the roof during the fully mechanized caving coal mining process. The conveyor 3 is located in the work space 2, and the conveyor 3 It is the rear conveyor. Usually, in the coal mining process, the coal cut by the shearer is firstly transported by the front conveyor, and then the coal that has been dropped from the upper part is transported out by the rear conveyor. After the coal is transported out, a goaf 4 is formed behind ...

A method for installing gob bundle tubes in a fully mechanized caving face, comprising step 1: determining the length of the fully mechanized caving face and the number of protective steel pipes sleeved outside the bundle tubes; The pipe is inserted into the protective steel pipe, and one end of the bundled pipe is fixed to the first protective steel pipe; Step 3: Connect the protective steel pipe to be transported with the previous protective steel pipe in turn, and the bundled pipe passes through multiple protective steel pipes; Step 4: Put the connected protective steel pipe on the conveyor, start the conveyor, and transport the protective steel pipe together with the beam tube to the goaf, when the tail of the protective steel pipe reaches the tail of the machine, stop the conveyor; step 5: repeat steps 3 and 4, Until the remaining protective steel pipes and bundled pipes are all transported to the goaf, the above installation method reduces the working time of the goaf, improves the efficiency, and greatly increases the safety of the operation, and the transportation process does not require additional equipment, saving costs .
Description
technical field [0001] The invention belongs to the technical field of coal mine safety, and in particular relates to a method for installing a goaf bundle tube in a fully mechanized caving working face for monitoring underground gas. Background technique [0002] There is a danger of natural fire in the underground goaf. Usually, the method of laying bundle pipes in the goaf is used to monitor the gas in the goaf. After analyzing the content of the index gas, it is speculated whether the gob is in danger of fire or whether it has already caught fire. Bundle tube monitoring can predict the fire situation in the goaf in advance, and take effective fire prevention and extinguishing measures to improve the safety factor of underground personnel. [0003] Nowadays, the laying of bundled pipes is a purely physical project with cumbersome procedures and high labor intensity. Construction personnel must carry out protection of steel pipes, carry bundled pipes, and connect protectio...
