Embodiment Construction
[0015] Such as figure 1 As shown, a cross-belt drilling method, which includes:
[0016] In the first step, a crawler-type traveling vehicle 3 is arranged on the side of the belt conveyor 2 in the roadway 1, and a working platform 8 spanning above the belt conveyor is arranged on the crawler-type traveling vehicle 3;
[0017] The second step is to take a column-type pneumatic drilling rig, and the column of the column-type pneumatic drilling rig is required to be designed as a hydraulic jacking column 6, and the hydraulic lifting column 6 is installed on the crawler-type walking vehicle 3, and the column The guide rail 9 of the pneumatic drilling rig is installed on the hydraulic jacking pillar 6 through the locking sleeve 7;
[0018] The third step is to install the pneumatic hydraulic pump 11 and the pneumatic two-position three-way valve 10 on the column-type pneumatic drilling rig; connect the hydraulic pipeline of the pneumatic hydraulic pump 11 to the hydraulic jacking ...

The invention discloses a method for drilling a hole across a belt conveyor. The method comprises the following steps: arranging a crawler type traveling vehicle with a working platform on one side of the belt conveyor of a roadway; mounting a pneumatic hydraulic pump and a pneumatic two-position three-way valve on a hydraulic trestle column type pneumatic drilling machine; connecting a hydraulic pipeline of the pneumatic hydraulic pump with a hydraulic type jacking strut; connecting one outlet of the two-position three-way valve with an air inlet of a drilling machine body, and connecting the other outlet of the two-position three-way valve with the pneumatic hydraulic pump; opening an air source, starting the trestle column type pneumatic drilling machine for drilling, and continuously operating a drilling rod on a construction platform by a constructor until the hole is drilled, so that synchronization of the drilling machine and the belt conveyor is realized, and operation interference is avoided. Due to the fact that the crawler type traveling vehicle stops on one side of the belt conveyor, the constructor drills the hole in the working platform across the belt conveyor to the opposite side, non-interference of the drilling machine and the belt conveyor is realized, coal mine production is not influenced, and the safety of the constructor is guaranteed.
Description
technical field [0001] The invention relates to drilling equipment used in underground coal mines. Background technique [0002] At present, for the mining face with the risk of impact, it is necessary to construct the pressure relief drilling in advance of the working face, so as to realize the relief of pressure and prevent the occurrence of rock burst. At present, during the construction of pressure relief drilling, it is generally completed by using a hand-held pneumatic drill, a column-type pneumatic drill or an electro-hydraulic drill. [0003] When drilling in the transportation roadway, because the belt conveyor (abbreviated as belt conveyor) is arranged in the transportation roadway, the space on both sides of the belt conveyor is limited, and the drilling rig is heavy and bulky, so it cannot be constructed on the side of the roadway wall. The drilling rig is placed on one side of the belt conveyor, and the drilling rig needs to cross the belt conveyor to touch the...
