NB/T 51028-2015Code for coal mine construction organization plan of coal industry (English PDF)

Foreword

This document was issued on 2 April 2015 by the National Energy Administration of the PRC and takes effect on 1 September 2015.

It is a NB/T standard: recommended rather than compulsory, but it is the text a Chinese reviewer applies when assessing a submission.

It is classified under ICS 73.020, Chinese classification P 00/09.

This code has been prepared in accordance with the requirements of the Notice of the National Energy Administration on Issuing the First Batch of the 2013 Compilation and Revision Plan for Energy Sector Industry Standards (Guo Neng Ke Ji [2013] No. 235).

Under that plan the China Coal Construction Association organised Shaanxi Coal and Chemical Industry Group Co., Ltd., China Coal Xi'an Design Engineering Co., Ltd. and other relevant units to carry out the compilation work.

In the course of the compilation the working group carried out extensive investigation and analysis, and summarised the experience gained in the Chinese coal industry over recent decades in the preparation and the management of mine construction organization plans.

The working group gave full consideration to the differing circumstances of the various regions and of the various enterprises, and worked on the basis of the relevant laws, regulations and standards in force.

The code was developed by revising and completing the document Code for Coal Mine Construction Organization Plan of Coal Industry (Trial), previously released by the China Coal Construction Association. After opinions had been widely solicited, the text was submitted to a final review and settled.

The code is made up of thirteen chapters. Its principal content covers general provisions, terms, basic requirements, the general construction arrangement, construction preparation, the general construction layout plan, the major unit projects, the main production system of the coal mine under construction, the master schedule, the management by objectives plan, safety and occupational health, green construction, and the attached charts and tables.

The National Energy Administration is responsible for the administration of this code, and the China Coal Construction Association is responsible for its day-to-day management.

Shaanxi Coal and Chemical Industry Group Co., Ltd. and China Coal Xi'an Design Engineering Co., Ltd. are responsible for the interpretation of the specific technical content.

Back matter

Explanation of Wording in This Code, page 40. This part explains the degrees of obligation attached to the auxiliary verbs used in the provisions, in the manner customary in Chinese engineering construction codes.

List of Standards Quoted, page 41. This part lists the standards referred to in the text of the code.

Addition: Explanation of Provisions, page 42. This is the explanatory annex to the provisions, printed as an addition to the code and giving the background and the reasoning behind the individual clauses.

The body of the code therefore runs to 39 pages, with the back matter beginning on page 40 and the explanation of provisions occupying the remainder of the volume.

The code is written as a mandatory-form engineering construction code: the provisions are numbered in the chapter-section-item manner customary for that class of document, and the explanation of wording on page 40 is the key to how each provision is to be read.

1 Scope

NB/T 51028-2015 governs the preparation of the construction organisation design for a coal mine - the document that sets out how a mine will actually be built before the first shaft is sunk. Sinking shafts and driving the main roadways is a sequential business in which one delay propagates through everything after it, so the organisation plan is what the whole construction programme and its resourcing rest on. The code sets the general provisions and the defined terms, then the content the plan must contain and the stage at which each part is prepared. It covers the analysis of the project conditions and the geology, the overall construction scheme and the critical path through shaft sinking, roadway driving and the surface works, the sequencing and the interfaces between them, the temporary works and site installations, the plant and labour required and their deployment over time, the materials and their supply, the ventilation, drainage, hoisting and power arrangements during construction, and the safety and environmental measures. The programme and its presentation, the site layout drawings, the technical and economic indicators used to judge the plan, and the appendices with their drafting outlines complete the code. Owners, contractors and reviewers of Chinese coal mine construction projects work to it.

Chapter 1 states the purpose of the code, the projects to which it applies, the conditions that the construction organization plan must take into account, and the relationship between this code and the other standards in force. It occupies page 1 of the standard and contains four provisions, numbered 1.0.1 to 1.0.4.

1.0.1 This code is formulated in order to standardise the preparation and the management of the construction organization plan for coal industry mines, and to raise the level of construction management of coal industry mines.

1.0.2 This code applies to the preparation and the management of the construction organization plan of newly built, reconstructed and extended mine construction projects.

1.0.3 The construction organization plan of a coal industry mine shall be prepared in combination with the geological conditions of the mine, its hydrogeological conditions, the conditions of the region and the characteristics of the engineering works.

1.0.4 The preparation and the management of the construction organization plan of a coal industry mine shall comply not only with the provisions of this code but also with the provisions of the relevant standards of the country currently in force.
