Abstract：In response to the engineering demand for the diversified pick arrangement design of pick-type rockbreaking equipment and the insufficient flexibility of existing test equipment in simulating multi-pick rockbreaking, a multi-mode linear rock-breaking test system for picks was developed. This system enables laboratory rock-breaking experiments by picks with various geometric shapes, quantity combinations, and cutting modes.The basic structure, main functions, and technical parameters of the test system were introduced, and rockbreaking tests under four working modes were cnducted for verification. The test system features the following advantages:(1) A structural design method for the pick arrangement system based on positioning plates allows for flexible arrangement of picks with diverse geometric shapes and quantities;(2) The spacing and angle of picks are adjustable, which enables single/multiple cutting processes of picks under different spacing and angle conditions and supports simulations on the multi-pick rock-breaking state of pick-type rock-breaking equipment in practical engineering scenarios;(3) The test system boasts good integrity, simple structure, convenient operation, and excellent expandability. The results of single-pick single/multiple rock-breaking tests, dual(triple)-pick single/multiple rock-breaking tests, and water jet-pick combined rock-breaking tests verify the ability of the test system to investigate the rock-breaking mechanisms and pick arrangement principles for pick-type rock-breaking equipment under conventional engineering conditions. Furthermore, it supports innovative research on the water jet-pick combined rock-breaking principle under hard rock working conditions. The research can provide a solid foundation for the diversified design of pick-type rock-breaking equipment and the improvement of rock-breaking efficiency.
