A Single Power Source Dual Channel Surrounding Rock Mining Fracture Detection System

Abstract

The invention belongs to the technical field of drilling and relates to a single power supply double-channel surrounding rock mining-induced fissure detection system, mainly comprising five function parts, namely a single power supply closed control platform, a single power supply leakage measuring platform, a platform support, a power supply double-channel connection device, and a single power supply double-channel surrounding rock mining-induced fissure probe; the single power supply closed control platform and the single power supply leakage measuring platform are connected in parallel through a hose 10 mm in diamet4er and then mounted on the platform support and are then serially connected sequentially with the power supply double-channel connection device and the single power supply double-channel surrounding rock mining-induced fissure probe through hoses 10 mm in diameter; the single power supply double-channel surrounding rock mining-induced fissure detection system is simple in structure and convenient to use, parts are light in weight, assembly is fast, the cost is low, the detection process is stable and accurate, and the system is particularly suitable for detecting growth of coal bed surrounding rock mining-induced fissures under complex underground conditions.

Description

Technical field: [0001] The invention belongs to the technical field of drilling, and relates to a single power source and double-channel surrounding rock mining fissure detection system. By detecting the development characteristics of surrounding rock fissures after coal seam mining, the development characteristics and evolution mechanism of coal seam surrounding rock fissures are studied in the coal mine production process. Background technique: [0002] At present, although the proportion of coal mines in my country's energy consumption continues to decline, its primacy has not been shaken. The safety issues involved in the mining of coal resources are still the key issues of safety supervision in my country's energy industry. During the mining process of the coal seam, due to the loss of the supporting function of the coal seam, the overlying roof, the underlying floor and the surrounding coal bodies in the goaf will be unstable, cracked, and moved under the action of min...
