Mine Shaft and equipment installation is a risk of pressure safety management, construction technology more integrated unit of work. Shaft equipment construction program, the installation of shaft equipment is a key core technology, construction equipment in the shaft should be completed before the start of an important technical preparatory work, is to exclude high-risk deep existence of various complex operating environment of the basic technology to ensure safety hazard for construction projects to ensure construction safety, construction quality, construction progress of the normal control, improve construction efficiency and reduce the construction cost of great significance. So in construction engineering organizations to develop the implementation plan should focus on the following questions.

1 demonstrate the principles of construction plan

Enhance the Mine Shaft shaft equipment is an important component of the system, as a lifting system also includes a large steel derrick floor, large fixed elevator equipment, and wellheads, downhole and other equipment. Shaft equipment in the project organization and implementation, in fact not as a separate unit installation and construction works, but a combination of various units of works, such as building needs under the mine shaft there may be invested ladder; wellbore drainage, pressure air, fire sprinkler, grouting, refrigeration cooling, gas drainage and other industrial piping; high-voltage power cable shaft, shaft voltage, communications, signal, control, monitoring cable installation unit project, with a large engineering, construction technology of complex, multi-process parallel job density, harsh operating environment construction, shaft security, quality control is difficult characteristics. multiple unit project with the synchronous assembly line shaft equipment construction, the construction unit of the mine which is the total duration of the construction requirements of a construction team can concentrate on the construction reflecting the organizational capacity and integrated technology can meet to meet the requirements of social and economic development is the construction unit by optimizing the overall construction plan, effectively speed up the construction schedule and reduce construction costs and improve the economic efficiency of the basic requirements. Therefore, to develop a good implementation plan, a comprehensive analysis should be considered all relevant factors, to the installation of shaft equipment, the development of the construction program began to follow the following principles: 1) to the project and considering the similarities and characteristics of similar projects, a preliminary feasibility of technical solutions, that is, the project technical planning ( detailed, comprehensive review of design and construction plans) .2) to consider the field of natural environmental conditions (the conditions survey and site construction, operating environment) .3) to consider to meet the requirements of the contract period (in the key line of work to take technical measures to shorten the construction period reasonable) .4) to consider the simultaneous construction of the technical feasibility and continuity (to ensure quality control, process node, the effective overlap construction) .5) to consider the construction organization and construction of technical equipment .6) to analyze, identify significant operating environment or key source of security risks, to take effective security precautions, and comprehensive security risk to consider every aspect of the construction elements of control requirements .7) construction program to determine the technical and economic evaluation.

2 Scheme Demonstration raw data required to complete a construction proposal, but also serious collection, collation, verification of the relevant raw data as follows: 1) design and construction drawings .2) construction of the required wellhead, downhole, wellbore construction positioning, measurement data .3) Mixed construction drawings and project related meetings Minutes Minutes .4) technical documentation and quality of norms, standards, .5) security regulations, rules, regulations, documents related to safety management informed .6) before the status of shaft equipment. If wellbore lien facilities, wall thickness and strength of concrete; sinking through sand layer over seam elevation location.

7) shaft ventilation and safety management requirements .8) Mine Shaft, watering conditions and measurements .9) shaft equipment prior to inspection records. The main shaft perpendicularity, concentricity, holes and other shaft equipment installation location of the defect inspection records .10) wellhead ground the original building, facility layout .11 cases) its own, you can swap and rental of equipment, testing, testing equipment breakdown .12) design drawings related to the material availability.

3 demonstrates the main points of the construction program

According to the principles and demonstration programs to collect raw data needed to develop a shaft equipment construction program should also address the following questions into account, these technical issues are the main contents of the construction program.

1) A container which improve and enhance the ways to deal with construction workers and into the well shaft and issues to enhance device security into clear project requirements, guarantee the safety of the construction.

2) construction workers needed in the wellbore construction platform (commonly referred to "multi-hanging plate", hereinafter referred to as hanging plate), hanging panel design structure and the structural strength and construction personnel safety issues, hanging plate can No construction schedule to meet the control and the amount of each class should be required to complete the project, meets the synchronization process of the construction process, is to ensure that the next process and the next construction requirements for continuous operations team.

3) How to achieve the standard layers and layers of non-standard shaft equipment and processes rapid conversion processes convert the effective overlap.

4) The materials required for construction of shaft equipment, components, methods adopted into the well to enhance the construction crane delivered to the disk position within the wellbore, the construction team to ensure the progress of work requirements.

5) Block wall before the installation of steel in the wall how to achieve fast measurement to determine the anchor positioning eyelets No location, how to quickly install the find is steel wall blocks, beam seat, pipe beams, pipes and other components, and the work required to accurately measure place.

6) How to solve industrial pipe into the well bore and well bore pipes to enhance the interface method of welding operations and welding operations required to solve the well bore power safe power supply problem.

7) To ensure the shaft equipment installation and construction quality inspection and control, construction safety control and prevention work should focus on resolving several key problems: a. ���� wire installation and measurement of process quality inspection and installation methods shall meet the quality specifications and standards at the same time facilitate the construction personnel to operate. b. wellbore suspended plate structure design and strength check. c. hanging plate well bore to enhance safety requirements. d. to enhance the temporary increase in the wellbore container chute, in what form to meet the enforce the relevant safety regulations. e. How to improve signal and visual layout of the temporary monitoring system. f. Wellhead closed disk temporary security arrangements, we must consider upgrading to meet the container, the material increase in the wellbore while the wellbore to ensure the safety of construction workers, in line with ventilation and safety management requirements; making use of steel forms and flame retardant materials, compliance with fire safety regulations. g. temporary suspension upgrade equipment and strength check of sizing and security. h. security management requirements for the ventilation shaft, and the Mine Shaft watering, sinking through sand layers or over seam section, must be the development of relevant safety technology. i. the construction site of the construction technology program involving environmental protection, occupational health and special measures.
