The proposal of the high-quality development strategy of the Yellow River Basin is of great significance for accelerating industrial agglomeration. This study takes 49 prefecture-level cities in the Yellow River Basin as the research object. Based on the panel data from 2006 to 2018, we used the location quotient to calculate the manufacturing agglomeration, the producer service industry agglomeration and the synergistic agglomeration in the basin. The spatial Dubin model of the impact of the three types of agglomeration on the economic growth in the basin was constructed. The Yellow River basin was divided into upstream, midstream and downstream to explore the regional heterogeneity of the impact of the industrial agglomeration on the economic growth. The result showed that (1) the economic development of the Yellow River Basin has a spatial overflow. The economic improvement of the surrounding cities promotes local economic growth—the manufacturing agglomeration, producer service industry agglomeration and synergistic agglomeration all promote economic growth. The effect of the manufacturing agglomeration is more significant than the others. (2) The impact of the industrial agglomeration on the economic growth in the Yellow River Basin presents an evident regional heterogeneity, and the magnitude and direction of the action vary in the different regions.
Rock failure is the root cause of geological disasters such as slope failure, civil tunnel collapse, and water inrush in roadways and mines. Accurate and effective monitoring of the loaded rock failure process can provide reliable precursor information for water inrushes in underground engineering structures such as in mines, civil tunnels, and subways. The water inrush may affect the safe and efficient execution of these engineering structures. Therefore, it is essential to predict the water inrush effectively. In this paper, the water inrush process of the roadway was simulated by laboratory experiments. The multiparameters such as strain energy field and infrared radiation temperature field were normalized based on the normalization algorithm of linear function transformation. On the basis of analyzing the variation characteristics of the original parameters, the evolution characteristics after the parameters normalization algorithm were studied, and the precursor of roadway water inrush was predicted comprehensively. The results show that the dissipation energy ratio, the infrared radiation variation coefficient (IRVC), the average infrared radiation temperature (AIRT), and the variance of successful minor infrared image temperature (VSMIT) are all suitable for the prediction of roadway water inrushes in the developing face of an excavation. The intermediate mutation of the IRVC can be used as an early precursor of roadway water inrush in the face of an excavation that is being developed. The inflection of the dissipation energy ratio from a declining amount to a level value and the mutation of VSMIT during rock failure can be used as the middle precursor of roadway water inrush. The mutation of AIRT and VSMIT after rock failure can be used as the precursor of roadway imminent water inrush. Combining with the early precursor and middle precursor of roadway water inrush, the graded warning of “early precursor–middle precursor–final precursor” of roadway water inrush can be obtained. The research results provide a theoretical basis for water inrush monitoring and early warning in the sustainable development of mine, tunnel, shaft, and foundation pit excavations.
