(4) ring the operation, inspection, maintenance and troubleshooting of slag raking machine, it is necessary to pay attention to relevant safety matters to ensure work safety
(5) under no circumstances should the slag scraper be operated by personnel without a license. When the slag scraper needs to stop working or replace the digging teeth or overhaul, it must be shut down according to the safety requirements
(6) in the work, we should refuse the instruction of illegal operation, and dissuade and stop others' illegal operation
(7) to actively participate in various safety activities, post technical training, improve safety awareness and skills, report accidents in time, and protect the scene
(8) have the knowledge of coal mine disaster prevention and self rescue, mutual rescue and on-site first aid, take safety and first aid measures immediately in case of accident, actively carry out self rescue and mutual rescue, prevent the situation from expanding, protect the scene, and report to the superior immediately
(9) strictly implement the on-site shift handover system. In addition to carefully filling in the operation log and accident records, the operation of the unit equipment in this shift should be told to the next shift driver in detail, so as to pay attention to the next shift processing and operation.
The suitable cross section of the tyre scraper is 1.6 * 1.6m; 1.8 * 1.8m; 2 * 2m section
suitable section of rail loader: 80 type 1.8 * 1.8m; 100 type 2.5 * 2.5m; 120 type 2.4 * 2.5m; 150 type, 2.5 * 2.8m; 160 Type 3.2 * 3.2m section. The selection of this model is mainly based on the mechanical equipment used to transport ore [such as rail transport, bucket car transport, shuttle car transport, etc.]
suitable section of crawler excavator loader: 80 type 2 * 2.2m; 100 type 2.6 * 2.6m; 100 type 2.2 * 2.4; 120 type 2.3 * 2.6m; 120 type 2.8 * 2.8; 150 type, 2.5 * 2.9m; 150 type 3.5 * 3.5m; 180 type, 2.8 * 3.3m; 180 type, 3 * 4m; 180 type, 4 * 4m; 200 type 4 * 4m; 220 type 4.5 * 4.5m; 260 type 5 * 5m; 312 type, 5 * 5m; 330 type 5 * 5m section
suitable section for inclined shaft with large slope: 80 crawler type 2.4 * 2.5m section with maximum working slope of 30 degrees; The maximum working gradient of 100 crawler type 2.6 * 2.6m section is 25 degrees; 120 crawler type 2.4 * 2.4m, maximum working gradient 28 degrees; 150 crawler type 3.5 * 3.5m, maximum working gradient 28 degrees; The maximum working gradient of 4 * 4m section of 180 crawler type is 32 degrees; 120 crawler type 2.8 * 2.8m, maximum working gradient 32 degrees; The maximum working gradient of 312 crawler type 5 * 5m section is 30 degrees
the main equipment commonly used in the construction of large section or full section are as follows:
rail transportation: gantry drilling jumbo, bolt support, vertical claw or rake bucket rail type rock loader (slag loader), 10 ~ 30 cubic shuttle mine car or mining big bucket car, 12 ton or 25t traction motor car, concrete spraying machine or transport pump, steel formwork jumbo combined supporting construction
trackless transportation: 3-arm or 4-arm tire and crawler electric hydraulic rock drilling jumbo, shotcrete anchor support, anchor jumbo, bucket crawler loader, 20 ~ 25 ton mining truck or pit truck [small secondary wheel and small Dongfeng], concrete spraying machine or delivery pump, integral steel formwork jumbo
the advantages of trackless shipping are high proction efficiency, good mobility, overcoming the practical advantages of working with large slope, small turning radius, strong working force, fast speed, not subject to conditions and so on. Although the initial investment is relatively high, the construction cost is low and fast, the engineering quality is good, and the safety and environmental protection are constantly improving. It is a common construction method in underground construction
push the handle forward to control the carrier cylinder to support the carrier through the directional valve to make the aggregate port touch the ground and support the front wheel. Press the conveying button, the contactor (20a) acts, the conveying roller starts to work, and drives the conveyor belt to start conveying
push forward or pull back the handle to control the action of the stick cylinder through the multi-channel directional valve, so as to drive the stick to rotate up or down around the hinge of the stick and the boom, so as to realize the extension or excavation. Push forward or pull back the handle to control the movement of the swivel cylinder through the multi-channel directional valve, so as to drive the digging arm to rotate to the right or left. Push forward or pull back the handle to control the action of boom cylinder through multi-channel directional valve to drive the boom to rotate clockwise or anticlockwise around its hinge axis with the support, so as to realize the boom lowering or lifting. Push forward or pull back the handle, and control the action of the digging cylinder through the multi-channel directional valve to drive the bucket to rotate up (outward) or down (inward) around the hinge of the bucket and the small arm, so as to turn the bucket back and forth, so as to realize the digging or unloading.
