Embodiment Construction

[0043] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0044] Such as figure 1 As shown, a project economic evaluation method of coal mine gas control trusteeship service mode includes the following steps:

[0045] S1: Enterprise quotas are compiled according to the quality of enterprise personnel, level of mechanical equipment, technology and management level, etc. The enterprise quota is organized by the construction enterprise itself, mainly based on the company's own conditions, including personnel quality, level of mechanical equipment, technology and management. Management level and other preparations, enterprise quotas are the foundation and basis for construction enterprises to carry out construction management and bidding quotations, and are also a concrete manifestation of the core competitiveness of enterprises. Therefore, it is necessary to formulate the consumption of manpower, m...

Abstract

The invention relates to an economic evaluation method of a coal mine gas control trusteeship mode project, comprising the following steps: S1, compiling enterprise quota according to enterprise personnel quality, mechanical equipment degree, technology and management level, etc.; S2: Calculating the engineering cost, including the total income and total cost of the gas control custody project, and the calculation method of the engineering cost adopts the bill of quantities method; S3: performing financial evaluation, obtaining the capital inflows and outflows from the beginning to the end ofthe project, as well as the predicted results of various economic indicators; S4: performing Sensitivity analysis, including unit price of engineering construction subcontracting, engineering construction quantity and collection period; S5: performing Risk evaluation; S6: performing Comprehensive evaluation, through the financial evaluation, uncertainty analysis of the project financial evaluationclassification, combined with the project risk quantitative evaluation of the project risk classification, performing comprehensive evaluation of the gas control engineering project,judging the feasibility of the project, and providing targeted measures.

Description

technical field [0001] The invention belongs to the field of underground gas prevention and control engineering in coal mines, and relates to an economic evaluation method for items in a coal mine gas control trusteeship service mode. Background technique [0002] Since 2005, the national coal mine safety production situation, especially the effectiveness of gas control has been significantly improved. However, we should also be soberly aware that although some mines are aware of the necessity of comprehensive gas management, due to the widespread problems of insufficient technical force, insufficient capital investment, insufficient management level and lack of engineering construction teams, coal mining enterprises It is necessary to rely on the support of professional service agencies for comprehensive gas management to solve a series of problems such as mine gas comprehensive management technology, construction and management. [0003] In order to meet the needs of rapi...
