PATENT SPECIFICATION FOR THE INVENTIONENTITLED:
A MEIM-based design method and system for support of a roadway
The invention is described in the following statement:-
A MEIM-based design method and system for support of a roadway
TECHNICAL FIELD
[0001] The invention relates to the field of stability control of roadway surrounding rock, in particular to a support design method and system of roadway surrounding rock based on MEIM.
BACKGROUND
[0002] In the process of construction and operation of various roadway projects, roadway support is a very important work, and it is also the key to control the stability of roadway surrounding rock, which has a great significance to maintain the safety of roadway construction and later operation.
[0003] The traditional roadway support design is based on geological data and roadway section form by combining experience and calculation. The given support scheme is usually to apply the initial set of support schemes provided for the whole roadway from the beginning till the end. Obviously, this set of support scheme cannot be applied to each section of the whole roadway, especially for roadways in complex geological conditions and changeable strata. Moreover, when the roadway is in operation, The engineering conditions around the roadway are also constantly changing, For example, a new roadway or chamber is added near this roadway, or the new roadway passes through the existing roadway, etc., so even the original support scheme, which is very suitable for the geological conditions of this section of roadway, cannot play a good role at this time, which is also the reason why the roadway often deforms and damages during operation. That is to say, the support scheme given by the traditional roadway support design method cannot meet the needs of surrounding rock stability control in each stage from construction to operation of the roadway, but the reality is that the support scheme given by the way of traditional roadway support design method is to deal with everything with a set of initial schemes. Therefore, under this condition, it is necessary to put forward the repair scheme of roadway according to the changed conditions. The changed conditions mentioned are: usually the support scheme is written according to the geological exploration report, but there are always different geological conditions from the report during the implementation process.
[0004] On the other hand, Whether the traditional roadway support design scheme and support parameters are appropriate and effective, It is impossible to make intuitive display and prediction before the project is implemented, It is also impossible to modify the supporting scheme and parameters in time according to the changed geological conditions and engineering conditions, and intuitively show the supporting effect, but need to be verified by engineering practice before making a judgment. Once it is not suitable, it will not only reduce the engineering efficiency and increase the cost, but also often endanger the engineering safety and even cause casualties.
[0005] Any discussion of the prior art throughout the specification should in no way be considered as an admission that such prior art is widely known or forms part of common general knowledge in the field.
