Embodiment Construction

[0032] The present invention will be described in detail below by taking the practical application of the method of the present invention in coal production as an example. However, those skilled in the art should realize that the present invention is not limited thereby.

[0033] Such as figure 1 As shown, a kind of method that the present invention proposes using regional power planning to control mine power energy source, comprises the following steps:

[0034] The first step is to use existing methods to determine the engineering technical plan for mining based on geological exploration data.

[0035] Mining needs to consider natural factors and engineering technical factors, among which natural factors include fracture division, roof lithology, coal seam structure, coal seam dip, coal seam thickness and mining depth; engineering technical factors include development methods and coal mining methods, and development methods further involve Mining liberated layer, mining d...

Abstract

The invention relates to a method for controlling mine power energy sources by using regional power planning, so as to realize the optimal combination of mine design, mining work and natural environment, and solve the current situation of passive prevention and control of mine power problems. The present invention uses the results of regional dynamic planning to establish an application method of regional dynamic planning in mines, obtains engineering technical solutions by combining regional dynamic planning, and performs computer simulation, comparative analysis, and selects the best plan with the smallest probability of occurrence of dynamic disasters. The prevention and control of dangerous areas is carried out, thereby improving the application status of regional power planning, realizing the combination of regional power planning and mining engineering, and the active prevention and control of mine power disasters.

Description

technical field [0001] The invention relates to the field of coal mining, in particular to a method for controlling the power source of the mine by applying regional power planning in mines with dynamic phenomena. Background technique [0002] The coal industry is a traditional high-risk industry, and various disasters and accidents occur from time to time. In recent years, mine dynamic phenomena including coal and gas outburst, rock burst and mine earthquake have become the main factors threatening coal mines. According to statistics, among the 724 key state-owned coal mines in my country, there are 152 high-gas mines, accounting for 21% of the total; 154 mines with prominent coal and gas, accounting for 21.3% of the total, and 1 / 3 of the world. In addition, among the 910 large coal mines in my country, there are 47 coal mines with risk of rock burst, accounting for 5.16% of the total. As of 2003, 102 coal mines have experienced mining earthquakes. [0003] At present, ...
