“…In China's coal mine tunneling, rock tunneling occupies about 20%, which has the characteristics of low efficiency and high risk of manual operation, completely restricting the development process of coal mine mechanization. Rock tunneling has drilling and blasting methods [1] , full-section hard rock tunneling machine method (TBM) [2] , and other construction technologies. For drilling and blasting method construction, drilling jumbo is widely used due to its high construction efficiency and large working range.…”

Based on the integrated structure characteristics of the double-arm drilling machine, there are two kinds of interference between drilling and excavation operations. Through the simplified calculation of the structure model of the left and right drilling arms, the drilling range of the double-arm drilling and loading machine is obtained. Through the calculation of the structure model of the excavation arm, the excavation range is obtained. The interference area and pure interference area exist in the operation range of the three working arms. Taking the drilling arrangement of the section of the 2556 north wing transport lane in Xinji No.1 Mine as an example, the drilling hole sequence to avoid interference is planned for the 52 drilling holes in the drilling range and interference range of the left and right drilling arms, which solves the operation interference of the three working arms and plans two optimal drilling hole sequences. It provides a reference for the subsequent industrial application of various types of drilling machines in coal mines.

The tunnel boring machine (TBM) is widely used in tunnel construction projects. The thrust system plays a crucial role to drive the machine ahead and support gripper shoes stably while tunneling. More and more attention has been paid to the pressure and velocity regulation efficiency as the TBM advances in complex rock conditions to ensure the stabilization of the tunneling process. A thrust hydraulic control system, assembled with a proportional pressure reducing valve, is established with system operating parameters. The mathematical model of the thrust electro-hydraulic system is revealed. To improve the control characteristics of the thrust system, a self-tuning fuzzy PID controller is introduced in the pressure and velocity regulation procedures. After that, tests on a Φ2.5 m scaled TBM test rig are carried out. The test results show that the thrust system adopting the fuzzy PID controller results in less oscillation and a smoother regulation process. It takes less time to reach the target goal of pressure regulation with less vibration during the pressure regenerating periods, and both systems of conventional PID controller and fuzzy PID controller are qualified in velocity regulation movements. The proposed control methods show better benefits in reduction of vibrations and shorter time of regulation to stable conditions, which extends the machine’s life and affects the acceleration of the tunneling process.

The thrust system of a tunnel boring machine plays a crucial role by driving the machine ahead and supporting the gripper shoes stably. A thrust hydraulic control system, assembled with a proportional flow control valve and a pressure relief valve, is established with system operating parameters. The mathematical model of a thrust electrohydraulic system is presented. To improve the control characteristics of the thrust system, a self-tuning fuzzy PID controller was introduced in synchronization motion control situations. To attain the best control parameters, three synchronization motion control systems were used to control the thrust propel cylinders. Tests on a Ø2.5 m scaled TBM test rig were carried out to verify the capabilities of the ISCS, SRSCS and CRSCS. Comparative tests were conducted, and the results showed that the thrust system adopting SRSCS achieved the least oscillation and the quickest response. The steady-state displacement error decreased by about 33.3% in contrast to the ISCS and CRSCS.
