Scope

Scope: This document provides the general requirements, methods and basis, processes and procedures, result analysis and application, and data management for predicting the risk of coal and gas outbursts in coal mining face during coal mining in coal seams using the drill cuttings index method, the composite index method, and the R value index method (collectively referred to as the drilling index method in this document). This document is applicable to coal mining enterprises using the drill cuttings index method, the composite index method, and the R value index method to predict the risk of coal and gas outbursts in coal mining face during coal mining in coal seams and for management purposes. Main technical content: This document outlines the general requirements, applicable scenarios, methods and basis, processes and procedures, result analysis and application, and data management for predicting the risk of coal and gas outbursts in coal mining face during coal mining in coal seams using the drilling index method. It emphasizes the requirement that the prediction work should implement full-process closed-loop management, and proposes recommendations such as using video monitoring measures for prediction drilling, ensuring that prediction instruments have storage and display functions, using dedicated drill bits and drill rods, collecting drill cuttings with specialized tools, and implementing informatized management of prediction data. The implementation of this document aims to promote the standardization and normalization of the drilling index method for predicting the risk of coal and gas outbursts in coal mining face during coal mining in coal seams, enhance the technical management level of coal mining enterprises in preventing and controlling coal and gas outbursts, and prevent the occurrence of coal and gas outburst accidents in coal mining face.
