技术领域technical field

背景技术Background technique
煤炭地下开采过程中井下煤岩体内瓦斯气体压力、瓦斯流量、温度、地应力是影响煤矿生产安全的重要因素。随着煤炭开采深度的增加，煤岩体瓦斯气体压力、瓦斯流量、温度、地应力逐渐增大。研究表明，煤炭深部开采冲击地压等动力灾害的发生与煤岩体物理力学性质密不可分，与地温和煤岩体赋存状态有关，是煤岩体瓦斯压力、瓦斯流量、温度和地应力耦合作用的结果。煤岩体瓦斯压力、瓦斯流量、地应力各种异常变化蕴含着动力灾害发生的前兆信息，同时，瓦斯压力、瓦斯流量又受到地温和地应力的影响。因此，对煤炭开采过程中井下煤岩体瓦斯气体压力、瓦斯流量、温度、地应力在多场耦合作用下的有效测试，能够有效提高煤矿动力灾害发生前兆信息的捕捉与分析，对于分析与预测煤炭深部开采诱发的动力灾害，具有重要意义与应用前景。In the process of underground coal mining, the gas pressure, gas flow rate, temperature and in-situ stress in the underground coal and rock body are important factors affecting the safety of coal mine production. With the increase of coal mining depth, the gas pressure, gas flow rate, temperature and ground stress of coal and rock mass increase gradually. Studies have shown that the occurrence of dynamic disasters such as rock burst in deep coal mining is inseparable from the physical and mechanical properties of coal and rock mass, and is related to the geothermal temperature and the occurrence state of coal and rock mass. result of the action. Abnormal changes in gas pressure, gas flow, and geostress of coal and rock mass contain precursory information of dynamic disasters. At the same time, gas pressure and gas flow are affected by geothermal temperature and geostress. Therefore, the effective testing of gas pressure, gas flow, temperature, and ground stress of underground coal and rock mass under the coupling effect of multiple fields in the process of coal mining can effectively improve the capture and analysis of precursor information of coal mine dynamic disasters. The dynamic disasters induced by deep coal mining have great significance and application prospects.
现有的设备与技术无法同时测试煤炭地下开采煤岩体的瓦斯压力、瓦斯流量、温度和地应力参数，导致目前对于煤炭深部开采多场耦合作用下动力灾害发生机理认识不足，煤炭开采难以避免因监测不及时导致动力灾害的发生。Existing equipment and technology cannot simultaneously test the gas pressure, gas flow, temperature and ground stress parameters of coal and rock masses in underground coal mining, resulting in insufficient understanding of the mechanism of dynamic disasters under the coupling of multiple fields in deep coal mining Avoid the occurrence of power disasters caused by untimely monitoring.
