Embodiment 1

[0044] Such as figure 1 as shown, figure 1 It is a working flow chart of a method for calculating gas emission in tunneling exposed tunnels provided by an embodiment of the present invention, including:

[0045] Step S11: Obtain the exposure days information and daily footage data information of the excavated exposed roadway;

[0046] Step S12: According to the exposure days information, the daily footage data information and the preset mathematical model, calculate the actual gas emission amount of the excavation exposed roadway.

[0047] Specifically, the mathematical model follows the rule that the gas emission from the measured tunneling exposed roadway gradually decreases with the increase of the exposure time, and it can never be zero. Exponential function of time change y=a*e -bx , represents a point from the initial exposure, as time increases the variation trend of the gas emission in the tunnel exposed roadway, so that the gas emission in the roadway exposed by th...

Abstract

The invention discloses a calculation method for gas emission amount of a tunneling exposed roadway, a storage medium and electronic equipment. The method comprises the following steps: acquiring exposure day information and daily footage data information of the tunneling exposed roadway; and calculating the actual gas emission amount of the tunneling exposed roadway according to the exposure dayinformation, the daily footage data information and a preset mathematical model. The exposure day information and daily footage data information of the tunneling exposed roadway are acquired, and theactual gas emission amount of the tunneling exposed roadway is calculated according to the preset mathematical model to increase the accuracy of the gas emission amount of the tunneling exposed roadway, so that a gas prevention scheme can be formulated pertinently; safety accidents are prevented; and the safety is improved.

Description

technical field [0001] The invention relates to the technical field of coal mine safety, in particular to a calculation method, a storage medium and electronic equipment for the amount of gas gushing out of an excavation exposed roadway. Background technique [0002] At present, with the rapid development of cloud computing and Internet of Things technology, big data is penetrating into more and more fields at an alarming rate. From large industries to small specific business issues, big data is playing an increasingly important role, and the value of big data is self-evident. [0003] The traditional calculation method of gas emission in excavation exposed roadway is calculated by the coal wall gas emission prediction formula of the separate source prediction method, the formula is as follows: [0004] [0005] Among them, q 3 is the amount of gas emission from the roadway exposed by excavation, D is the perimeter length of the exposed coal wall in the roadway section,...
