Embodiment 1

[0048] see figure 1 , this embodiment provides an intelligent decision-making method for coordinated development of coal and coalbed methane, including the following steps:

[0049] 1) Establish an evaluation index system for coordinated development of coal and coalbed methane. The coordinated development of coal and coalbed methane can be regarded as a total system composed of the mutual coupling and coordination of the coal mining subsystem and the coalbed methane extraction subsystem. Therefore, the evaluation index system for the coordinated development of coal and coalbed methane can be regarded as the joint composition of the coal mining evaluation index system and the coalbed methane extraction evaluation index system. The coal mining evaluation index system can be divided into development area and production area from the perspective of time and space. From the perspective of time and space, the evaluation index system of coalbed methane drainage can be divided into ...

Embodiment 2

[0091] The main steps of this embodiment are the same as those of Embodiment 1, wherein, in step 5), the coupling coordination degree of coordinated development of coal and coalbed methane is compared with the coupling coordination degree classification table. The classification table of coupling coordination degree is shown in Table 1. Y is calculated due to i The value is between 0 and 1, therefore, the obtained coupling coordination degree value is also between 0 and 1. When D=0, the degree of coupling coordination is extremely small, and the systems or systems are in a state of irrelevance and incoordination, and the system will develop in the direction of disorder. When D=1, the degree of coupling coordination is the largest, and the two systems cooperate with each other and develop harmoniously, which is in the most ideal state. Therefore, the median segmentation method is used to classify the degree of coupling coordination.

Embodiment 3

[0095] The main steps of this embodiment are the same as those of Embodiment 1. In this embodiment, a numerical model for the coordinated development of coal and coalbed methane is constructed by means of Fluent numerical simulation.

[0096] According to the actual operation situation of the mine coal and coalbed methane coordinated development site, the evaluation index parameters of the coal and coalbed methane coordinated development system are obtained, and the coupling coordination degree of the mine coal and coalbed methane coordinated development is calculated.

[0097] Using Fluent software to simulate the coordinated development process of mine coal and coalbed methane, obtain the numerical model of coal and coalbed methane coordinated development, and obtain the evaluation index parameters of coal and coalbed methane coupled coordinated development and the coupling coordination degree of coal and coalbed methane coordinated development under numerical simulation .

Description

technical field [0001] The invention relates to the field of mine engineering, in particular to an intelligent decision-making method for coordinated development of coal and coal-bed methane. Background technique [0002] Coal and coalbed methane co-exist from the same source, and through rational development and utilization of them, they can become valuable clean energy. However, the coal seams in most coal mining areas in my country have a certain degree of prominent danger, which brings huge pressure and challenges to the safe production of coal mine production operations. Therefore, in the process of coal mining in my country, how to safely and efficiently deal with coalbed methane in coal seams is a crucial problem to be solved in coal production operations, which is also determined by the current situation of my country's coal resources. Today, in view of the key technical issues of how to develop and utilize coalbed methane resources efficiently and rationally, my co...
