Product Name: GD60 water bag coal mine explosion proof instructions GD60 water bag Usage: 1, the water shed water: Explosion Hydration (slot) shed into centralized and decentralized (based on layout dependent). Centralized water bag (slot) shed water species calculated by the roadway, the main water shed less than 400L / m 2, the auxiliary water shed less than 200L / m 2; decentralized water tank (bags) shed by shed Road Lane area occupied space volume calculations; less than 1.2L / m 3. 2, boron position settings: (1), water bag (slots) should be set up in the studio straight roadway; (2), hydration (slot) shed fork junction with the roadway, should be kept at a distance turning 50-70m, damper must be greater than the distance 25m; (3), first row from the water shed and face focus must remain 60-200m, from the first row of decentralized water shed and face must remain 30-60m; (4) , should be located in the auxiliary water proof shed roadway should be set multiple water shed, each spaced not more than 200m; 3, shed row between water and water shed area length from the shed: (1) centralized water shed row between distance of 1.2-3.0m, distributed along a roadway covered scattered arrangement of the spacing of two Hydration (grooves) group is 10-30m; (2), the length of central shelf area is not less than the main water shed 30m, centralized Auxiliary shed zone length is not less than 20m, decentralized shed zone length is not less than 200m.
