An online stress monitoring system is used to obtain a stress distribution of each position, a geophone monitoring system is used to monitor high-frequency vibration signals produced by coal and rock fracture, a support resistance monitoring system is used to monitor working resistance of hydraulic supports in a working face, a well-ground joint microseismic system is used to monitor low-frequency vibration signals produced by the coal and rock fracture, and realize position of a microseismic source and inversion imaging of mining fractures, and an anchor stress monitoring system is used to monitor stress states of anchor bolts and cables. A data processing center is used to comprehensively process data obtained from the above five systems using an early warning model, thereby to obtain a prediction result of rock burst and determine whether to make early warning, thus workers can take timely measures according to the early warning situation.

Self-aligned interconnect structure and method of forming the same

The present disclosure provides an exemplary semiconductor structure that includes a substrate having a conductive feature disposed in a top portion of the substrate, a metal line above the substrate and in electrical coupling with the conductive feature, a dielectric feature disposed on a sidewall of the metal line, an etch stop layer disposed on the dielectric feature and the meta line, and a via extending through the etch stop layer and in physical contact with top surfaces of the dielectric feature and the metal line. The metal line has a first metal, and the via has a second metal different from the first metal. The top surface of the dielectric feature is higher than the top surface of the metal line.

Memory device for realizing sector erase function and operating method thereof

A memory device comprises a plurality of sectors and a driving circuit comprising a global word line driver and a first local word line driver. The global word line driver applies an erasing voltage to a selected sector of the sectors via a global word line. The first local word line driver, coupled to the global word line, drives a first local word line of the selected sector with a biasing voltage, so that the first local word line has a first voltage level corresponding to a non-erased state.
