MineHaul, Mine-Haulage Discrete-Event Simulation
Published:
An open-source Python package (minehaulsim) for deterministic discrete-event simulation of open-pit and underground mine haulage on constrained road networks, with seeded parametric mine generators. It is the companion generator for DispatchLab, MineHaul builds and simulates the mines, DispatchLab consumes and optimizes them. On PyPI (v0.10, Apache-2.0) with a documented API, CLI and docs wiki.
Real engine, synthetic mines, said plainly
The discrete-event engine and its physics are genuine and hand-verified: rimpull/retarder speed-by-grade, emergent truck bunching, routing on a constrained network, five dispatch baselines. Every run passes named validity gates and is byte-deterministic (asserted in CI, 227 tests on Linux + Windows). The mines are synthetic, seeded generators produce realistic structure with fabricated data, and equipment values use public spec magnitudes with class-representative, not OEM, curves.
Honest scope
It is early (Alpha) and deliberately bounded: it does not predict or optimize a real operation (no calibration, that is DispatchLab’s role), its physics anchors are qualitative literature orderings used as tests, and its novelty claim keeps its qualifier, the first open-source package to do mine haulage on a genuinely constrained road network (commercial closed tools exist).
