First, the project overview:
1. Project Name: Installation of the next group of coal drainage, pressure and sprinkler pipelines
2. Construction unit, supervision unit and construction unit:
Construction unit: Sanjiaohe Coal Mine
Supervisory unit: Mine Electromechanical Section
Construction unit: Water Control Team
3. Project content:
(1) Drainage pipeline installation plan
1) Two sets of 8 inch and two 6 inch pipes are installed in the lower coal belt lane and track lane. The belt lane is fixed with a 22# I-beam every 5 meters to fix the pipeline. The track lane is fixed by the top of the anchor and a set of anchors is used every 5 meters. At present, two 趟 8 inches, two 趟 6 inches per 趟 3600 meters have been completed, the next group of coal water bins are divided into two warehouses inside and outside, and the pump house is equipped with four D280-43*4 multistage centrifugal pumps, which are two 趟 8 inches. After the main inclined shaft, discharge to the sewage treatment station. (pipeline subtotal 14400 meters each 6 meters long)
2) The drawing of the pipeline installation part in the pump room (with the connection diagram of the pipeline and the valve) requires 14 valves, 4 check valves for the elbow 10, 2 valves for 2 inches, and 20 valves for the pipeline in the roadway. Elbow 20.
3) Install the fixed beam on the belt lane, and fix the beam to the inside of the roadway to fix it. (The beam is 22cm I-beam) The 3600m roadway needs 660 pieces per 5m to be used as the supporting pipeline beam.
4) The track lane is fixed by the anchor channel steel roof, and a set of anchors is made every 5 meters in the 500-meter roadway.
(2) Installation of the compressed air piping scheme
1) Installation position The main inclined shaft strong belt lane to the second group coal second belt tail, from the next group of coal 1100 meters substation using the three links to the next group of coal east and west track lanes to extend to the end. The pressure air line is made of 6-inch seamless steel pipe, and is laid on the other side of the pedestrian ladder at a distance of not less than 300mm from the bottom plate. The belt lane is fixed by a 22# I-beam every 5 meters. The track lane is fixed by the top of the anchor and a set of anchors is used every 5 meters. The pipelines must be laid flat and straight, and all the screw holes on each flange must be bolted, and the bolts are properly tightened. The gaskets are fully flexible and have no jamming and no air leakage. The total length is 5,000 meters.
2) Set a gate valve every 50m to facilitate other work in the later stage.
(3) Sprinkler pipe installation plan
1) The sprinkler pipeline installation and the pressure air pipeline are simultaneously in the same position and direction as the pressure air pipeline, and the construction method is the same as the pressure air pipeline. The total length is 5,000 meters.
2) Set a gate valve every 150m to facilitate other work in the later period.
Second, the construction organization:
Project installation person in charge: Zhang Shimin
Project Supervisor: Bai Kaijun
Person in charge of the measure: Yan Mingming
Main members: Hao Cunqi Lian Wei Fan Suogang Zhao Hongan
Third, construction progress and procedures:
Start-up time: May 2011, June time: the end of November 2012
The first stage: the belt lane fixed beam.
The second stage: installation of the belt lane.
The third stage: the track lane is fixed with a fixed anchor.
The fourth stage: the installation of pipelines in the track lane.
Fourth, security technical measures:
1. According to the “Safety Regulations for Coal Mines†and the design requirements for pipeline installation, construction and installation shall be carried out in strict accordance with the standards.
2. Strictly implement the mine leadership system to ensure that each mine-level management cadre in each class takes the class on site, strengthens on-site management, conducts hidden danger investigations, and finds problems in a timely manner.
3. According to the regulations, all the special types of work required are fully equipped, and all of them are certified to work.
4. Participants must carefully study the installation measures, and the team should carefully organize the employees to learn the various processes, understand the construction steps, and do self-protection and mutual insurance during the construction process.
5. The sound and light signals of the system should be complete. The safety facilities of “one slope and three gears†should be complete and effective, and keep normal use. The safety personnel should strengthen supervision and inspection, and the use of “one slope and three gearsâ€.
6. When the material is being cut, it is not allowed to be ultra-high and super wide, and the binding is firm. If necessary, personnel should be arranged to monitor the top of the mine car.
7. The materials and equipment placed in the wellbore should be fixed in a firm and reliable manner to prevent sliding or rolling down.
8. When the material is released or lifted downhole, the personnel in the wellbore should enter the shelter to avoid it.
9. High-altitude workers must wear seat belts and fix them in a firm and reliable location.
10. When lifting and installing fixed equipment, the handling equipment must be under the supervision of the vice captain. Under the personal command of the team leader, the passwords are unified and the actions are consistent to prevent accidents involving equipment bruising and crushing.
11. Before the construction, the construction site must be carefully inspected, knocked to help the top, and all unsafe factors must be handled before the operation can be carried out.
12. During the construction period, the person in charge of the site shall be under the unified command, and the participants must cooperate with each other.
13. Arrange a safety officer to enhance the inspection of the wells in each shift, check whether the various types of work and processes are carried out in accordance with the safety regulations and operating procedures, and strictly prevent the occurrence of “three violations†and increase the “three violationsâ€. The penalties for behavior.
14. When electrical oxygen welding is required, safety technical measures must be formulated in advance, and implementation should be carried out to the construction personnel, and the relevant departments should be notified to follow the work. After the operation is completed, the finishing work should be carried out in strict accordance with the requirements of the measures.
15. Other unfinished matters Strictly implement the relevant requirements of the “Safety Regulations for Coal Mines†and “Operational Regulationsâ€.
