支护工程质量检测系列仪器是井下巷道支护工程稳定性和施工质量检测最常用的仪器。我国煤矿井下巷道支护常用的检测仪器,如锚杆拉力计、混凝土强度检测仪、收敛计和数字压力表等,存在着规格单一、无系列产品、可靠性差、体积大或输出能力小等问题。本项目通过对现有常用检测仪器的开发创新、完善提高取得成果。 Support engineering quality testing series of equipment is underground tunnel supporting engineering stability and construction quality testing of the most commonly used instruments. Commonly used testing instruments for coal mine roadway support, such as bolt tension meter, concrete strength tester, convergence meter and digital pressure gauge, etc., exist single-specification, non-series products, with poor reliability, bulky or small output capacity and other issues . The project through the development of existing common testing instruments and innovations, improve and improve results achieved.
